An Overview of Current-Balancing Techniques

HENRY SHU-HUNG CHUNG and RUIHONG ZHANG

(LEDs) become the next generation of light source. High-power LED lamps usu-ally consist of many low-power LED units or modules connected in the form of multiple parallel-connected strings. This article provides an overview of the various current-balancing techniques for paralleled LED strings.

LEDs offer high luminous efficacy, long life expectancy, and simple

driving requirements, and they are mercury-free [1]. For lighting equipment requiring high luminous output, such as roadway lighting, each lamp typically consists of many low-power LED units or modules together with light diffusers for providing evenly dis-tributed illumination and facilitating management of the heat produced by the LEDs. The most straightforward way of operating the LEDs is to connect them in series to form a string, so that the current through each LED is the same. However, for lamps with many LEDs, the voltage of the string would be too high. Instead of using the single-string structure, LEDs are sometimes configured to form multiple parallel-con-nected LED strings. Each string has several series-connected LED units or modules. The number of strings, string voltage, and string current are designed by matching with the driving capability and specifications of the front-end driver.

Figure 1 shows the voltage–current characteristics of an LED. The forward voltage can have ±30% tolerance for a given forward current [2]. In other words, as illustrated in

Figure 1(a), the current flowing through two LEDs, LED1 and LED2, can be signifi-cantly different for the same forward volt-age. The current through L ED1 is more than twice the current through L ED2 when the forward voltage is 2.5 V [3], [4]. Figure 1(b) shows the relationship between the light illumination and the current flowing through the LEDs [5]–[7]. The luminous output is near-linearly pro-portional to the LED current. Thus, if sev-eral LED strings are connected in parallel and their string voltages are the same, the currents through the strings can be of different magnitudes. Apart from caus-ing uneven luminous outputs from the strings, some strings might also be over-driven, and thus, the lifetime of the LEDs will be deteriorated. Together with the negative temperature coefficient charac-teristics of the forward voltage of L EDs [8], there would be a significant current imbalance if the strings are simply con-nected in parallel. It is crucial to stabilize and balance the string currents.

There is a large body of literature on current-balancing technologies. As shown in Figure 2, the technologies can be classified into two main approach-

es—passive and active. The passive

approach is based on using passive

components, including resistors [9],

capacitors [11]–[18], inductors [19],

or transformers [20]–[33], to balance

the string currents, while the active ap-

proach is based on operating the active

devices in linear or switching mode to

control the string currents [35]–[49].

Operating Principles of Various

Current-Balancing Techniques

The concepts of various current-balancing

techniques are described as follows. They

are mainly based on using passive or ac-

tive devices, or a combination of them, to

share or control the string currents.

Current-Balancing with

Passive Devices

The basic principles of using passive de-

vices to perform current balancing are

largely based on three techniques: 1) the

current-division property of different im-

pedance paths in a parallel circuit, 2) the

charge (amp–second) balance property

of capacitors, and 3) the volt–second

balance property of inductive devices.

Some proposals combine those tech-

niques to deal with more strings and

reduce the component counts. The op-

erating principles of the techniques with

passive devices are described here.

Use of Resistors

The simplest passive-type current-

balancing technique is based on insert-

ing a resistor in series with each string

[9]. The circuit structure is shown in

Figure 3. The supply in Figure 3(a) is

a dc voltage source, while the one in

Figure 3(b) is an ac voltage source. The

element X in Figure 3(b) is a resistor. The

current-balancing function is achieved

by the feedback mechanism between the

string current and the positive tempera-

ture coefficient of the resistor. When the

current through a string is increased,

the power dissipation of the connected

resistor will increase. Then, the voltage

across the resistor will increase, and the

string current will be reduced. The idea

is similar to the current-sharing method

for paralleling multiple bipolar junction

transistors (BJTs) [10], in which each

transistor has a resistor connected in

series. Although this method is simple,

it is energy inefficient, less suitable for

dimming operation, and has a limited

operating range.

Use of Capacitors

Another passive element for the current

balancing of multiple LED strings is the

capacitor. The concept can be classified

into two main approaches. The first is

based on the charge-balance property of

capacitors [11]–[14], while the second

is based on the relative reactance of the

capacitor with respect to the equivalent

resistance of the associated LED string

[15]–[18]. The first approach is achieved

by the charge balance of capacitors in

the positive and negative half-cycles

through two separate LED strings.

Figure 4(a) shows the basic unit [11],

[12]. Each string has the same average

current. If more LED strings are needed,

more basic units are duplicated. Then,

the driving currents of the units will be

balanced by using transformers [20],

[27]. Figure 4(b) shows an extended con-

cept [13] in which the current- b alancing

capacitors are shared. Figure 4(c) shows

FIGURE 1 – The characteristics of an LED: (a) the voltage–current characteristics [2]–[4] and (b) the light output versus current [5]–[7].

FIGURE 2 – The classification of current-balancing techniques can be broken into two major types, passive and active.

another extended concept [14] in which the structures are linear type (without ca-pacitor )C N 1 and loop type (with capaci-tor ).C N 1 The charging and discharging of capacitors is realized by controlling the conduction time of the series switch in each LED string.

The second approach is based on de-signing the reactance of the capacitor so that it is larger than the equivalent imped-ance of the LED strings. In Figure 3(b), the element X is a capacitor . Thus, the capaci-tor current is largely determined by the reactance of the series capacitor [15]–[18]. The average current through the two strings associated with a capacitor will be the same due to the amp–second https://www.wendangku.net/doc/f35147139.html,e of Inductors

Figure 5 shows the single-switch topologies using inductors as the current-balancing

element [19]. Figure 5(a)–(c) shows the buck-, boost-, and buck–boost-derived topologies, respectively. The switch is operated in such a way that the induc-tor currents are discontinuous. Thus, the peak inductor current is determined by the values of the inductors, input voltage, and duty cycle of the switch. The string voltage only affects the duration of the freewheeling period of the associated di-odes before the corresponding inductor current becomes zero. Thus, the average current through each string is theoreti-cally determined by the value of the as-sociated inductor .

Use of Transformers

The idea of transformers for current-balancing is based on the volt–second balance to govern the currents through the primary and secondary sides of the transformers. Ideally, the primary- and secondary-side currents are in a fixed ratio. The structures can be further classified into the following methods: ■the series-connected transformer structure [Figure 6(a)] [20], [21] ■ a transformer with multiple out-puts [Figure 6(b)] [22], [23]

■the Huffman-tree-like transformer structure [Figure 6(c)] [24]–[26] ■the open-chain transformer struc-ture [Figure 6(d)] [27]–[29]

■the daisy-chain transformer struc-ture [Figure 6(e)] [30]–[33].

In Figure 6(a), the primary windings of the transformers are all connected in series so that the input current and, ideally, the output currents, have the same value. The structure shown in

F igure 6(b) applies the same principle as that in Figure 6(a). Figure 6(c) shows a

FIGURE 5 – The current-balancing methods with inductors [19]: (a) the buck-derived topology, (b) the boost-derived topology, and (c) the buck–boost-derived topology.

FIGURE 3 – The current-balancing methods with resistors or capacitors: (a) with a dc source [9] and (b) with an ac source [15]–[17].

Huffman-tree-like cascaded transformer structure. The first transformer in the tree has the highest current magnitude. Then, the current magnitude will reduce with the cascade level. Figure 6(d) and (e) shows the open- and daisy-chain trans-former structures, respectively. The idea is based on using a transformer to cou-ple two adjacent strings. Thus, all trans-formers carry the same current. The difference between the daisy- and open-chain structures is that the d aisy-chain structure requires one transformer more than the open-chain structure for coupling the currents between the first string and the last string. The advantage of the daisy-chain structure can effec-tively minimize the adverse effect of the magnetizing inductance of the trans-formers on the current-balancing per-formances. Moreover, the total volume of the transformers is reduced with the daisy-chain structure. A detailed discus-sion is given in [34].

Current-Balancing with Active Devices The active approach employs BJTs or metal–oxide–semiconductor field- e ffect transistors (MOSFETs) to control the string currents. Figure 7(a) shows the structure, with each string having a series-connected current regulator. The current regulator can be a simple BJT or MOSFET operating in the linear region. The L ED string current is controlled to be continuous. By controlling the bias-ing condition of the transistors, the cur-rent through the string is regulated by current mirror [35]–[41] or individual string current sensing [39], [41]. L i et al. [39] propose the self-configurable current reference for the current mirror

to enhance the current controllability.

In [41], a self-adaptive dc bus voltage is

proposed to ensure the overall energy ef-

ficiency. The main idea is to reduce the

voltage difference between the supply

voltage and the string voltage. In Figure

7(b), the current regulator is operated

in switching mode. The duty cycle of the

individual switching device is controlled

by a feedback mechanism through sens-

ing the string current and generating the

gate signal to the switching devices so as

to regulate the average string currents

[42], [43]. Meanwhile, the L EDs can be

operated with pulsewidth modulation

(PWM) dimming through controlling

the duty cycle [42]–[46]. In Figure 7(c)

and (d), every LED string is driven by a

dc–dc converter. Figure 7(c) shows the

structure with the inputs of the regula-

tors connected in parallel [47], [48],

while Figure 7(d) shows the one with the

inputs connected in series [49].

Comparisons

The six passive and active current-bal-

ancing methods categorized in Figure 2

each have their benefits and limitations.

In terms of the circuit complexity and

cost-effectiveness, the passive tech-

niques are more advantageous than the

active techniques. However, all passive

techniques, except using resistors, re-

quire high-frequency driving sources for

meeting the requirements of the amp-

second or volt–second balance proper-

ty. In other words, the use of a switching

network to operate is unavoidable with

the passive-type current- b alancing cir-

cuits. Nevertheless, as only one driving

source is usually needed, the required

number of switching devices is still

fewer than that required in the active

approach. The justification will take sev-

eral factors into consideration, such as

the number of strings, cost implication,

life expectancy, electrical specification of

the drivers, and operating environment.

Among all methods using passive de-

vices, the most cost-effective and sim-

plest is the use of resistors (Figure 3).

However, the major concerns include

the power dissipation in the resistors,

range of the allowed string voltage vari-

ation, and performance under dimming

condition. By replacing the resistors

with capacitors [Figure 3(b)], the ener-

gy efficiency is improved. However, as

the current-balancing function relies on

using a large reactance (small capaci-

tor) to lessen the effect of the string

voltage variation, it will increase the

reactive power and circulating energy

in the LED driver. The current-sharing

performance will be affected by the

variation of string voltage, in particular,

under abnormal conditions.

Instead of using a large impedance

ratio, the input currents of the basic

units for current-balancing dual strings

in Figure 4(a) are balanced by external

means [20], [27]. The improved cir-

cuit depicted in Figure 4(b) extends to

multiple strings. Moreover, the key ad-

vantage of this technique is that the cur-

rent-balancing property is less affected

by the tolerance of the capacitors and

the string voltages. However, the num-

ber of L ED strings must be an even

number. The number of LED strings in

the improved circuit in Figure 4(c) can

like structure [24]–[26]; (d) an open-chain structure [27]–[29]; and (e) a daisy-chain structure [30]–[33].

be odd, but the circuit complexity and implementation cost will be increased.

The complement of the capacitor is the inductor, which has a long lifetime and can be operated at a high tempera-ture. The method employing the volt–second balance of inductors (Figure 5) requires the inductor currents to be dis-continuous during operation. Thus, the switching device has a high peak current, increasing with the number of strings as well. Moreover, the duration of the free-wheeling stage (i.e., when the switching device is off) is string- v oltage dependent. The inductor current might become continuous if the energy stored in the inductor is not completely transferred to the associated string in the freewheel-ing stage. The duty cycle and switching frequency of the switching devices have to be controlled. Finally, the current-bal-ancing performance is dependent on the values of the inductors, as the inductors share the same switching sequence.

An extension of the inductive device is the use of transformers. The series-connected structure in Figure 6(a) is a straightforward technique. However, as all transformers are connected in se-ries, the total string voltages reflected to the primary side give the necessary driving voltage requirement. Moreover,

the large variation in voltage across

each string due to tolerance or abnor-

mal L ED operation pose challenges

for the designer. The idea of using a

transformer with multiple outputs

in Figure 6(b) is similar to the one in

Figure 6(a). The number of strings sup-

plied by the transformer is determined

by the volume of the transformer as

the windings are wound on one core.

Nevertheless, it is possible to combine

the concepts in Figure 6(a) and (b) to

increase the number of strings and re-

duce the number of transformers. The

transformer in the first level of the Huff-

man-tree-like structure [Figure 6(c)]

has the highest current stress. Then,

the current stress decreases as the

level propagates. Similar to the charge-

balance technique, the number of LED

strings is an even number. The coupling

devices have the same current rating in

the open- and daisy-chain structures.

Comparing the daisy-chain structure

[Figure 6(e)] to the open-chain struc-

ture [Figure 6(d)], the total volume

of the transformers used in the daisy-

chain structure is smaller than that of

the open-chain structure [34], even if

it requires one transformer more than

the open-chain structure. Finally, the

magnetizing inductance and tolerance

of the coupling transformers cannot be

ignored in the design, as they can sig-

nificantly affect the current coupling.

The merit of using a current regulator

for each string [Figure 7(a)] is its high

accuracy and controllability in control-

ling the string current. Moreover, those

techniques are amenable to large-scale

monolithic integration. For current regu-

lators operating in linear mode, the main

challenge is the minimization of the volt-

age across the current regulators. Thus,

some techniques, like adaptable dc bus

voltage and self-configurable current ref-

erence, have been proposed to ensure

high efficiency in current balancing. For

current regulators operating in switch-

ing mode [Figure 7(b)], the voltage rat-

ing of the series device is at least the

same as the bus voltage, as the worst-

case scenario is that the L ED string

voltage is zero. Finally, the most flexible

method is the use of a converter for

each string [Figure 7(c) and (d)]. Each

individual string current can be flexibly

controlled by adjusting the switching

frequency and duty cycle, but at the ex-

pense of increasing the circuit complexi-

ty and cost. Table 1 shows a comparison

FIGURE 7 – The current-balancing methods using active devices: (a) with linear current regulator [35]–[41]; (b) with a PWM current regulator [42], [43]; (c) with all regulator inputs connected in parallel [47], [48]; and (d) with all regulator inputs connected in series [49].

of the components required in the afore-mentioned methods.

Other Considerations

Apart from the current-balancing func-tions, many techniques have also placed emphasis on the operation of the driver under abnormal situations. The abnormal situations mainly con-tain two scenarios.

■Scenario 1—when an/some L ED(s)

in a string fail(s) open circuit, the

string current will be interrupted.

■Scenario 2—when an/some L ED(s)

in a string fail(s) short, the string

voltage will be reduced.

For scenario 1, the common method is to connect a bypass device, such as thyristor, across each LED. When an LED fails open, the associated bypass device will be triggered and provide a path for maintaining the string current flow [14], [32], [33], [35], [50]. The other ways are to isolate this string from the system by a module-string isolation network [40], turn

off the entire system by a protection cir-

cuit [16], or share the input voltage by the

remaining cells with the input of the short-

circuited cells [48].

For scenario 2, the LED string volt-

age variation will increase, and thus

the string current variation might also

increase. When the whole string fails

short, the effective method is to iso-

late the failed string from the system

by a module-string isolation network.

To maintain the current-balancing

function of the transformer structure,

an energy recycling network is added

[30]–[33]. Therefore, the transformer-

isolated driver in [32] and [33] can

regulate the current through the last

healthy LED, even if all other LEDs in

the lamp fail either open or short.

Conclusions

An overview of current-balancing tech-

niques for paralleled L ED strings has

been presented. The techniques can be

classified into two main approaches:

passive and active. The techniques have

their respective merits and limitations in

terms of circuit complexity, cost-effec-

tiveness, and controllability. Apart from

the c urrent-balancing function, it is equal-

ly important to take operation under ab-

normal string operation into account.
