Stream Ia will also be remained unchanged.
In above process, the function of having described each unit of the first power module 11 in detail, below in conjunction with specific
Embodiment, the function of each unit of second power supply module 12 is described in detail.

Electric current) switch to voltage signal Vi ', by voltage signal Vi ' outputs to signal amplification unit 122.
Signal amplification unit 122, for being amplified processing to voltage signal Vi ', to obtain voltage signal Ve ', and will
Voltage signal Ve ' outputs are to voltage comparison unit 125 and output isolated location 123.
Isolated location 123 is exported, is used for receiving voltage signal Ve ', and voltage signal Ve ' is exported to flow equalizing circuit 13,
And the voltage signal Vs for the generation of flow equalizing circuit 13 to be isolated, the voltage signal Vs that flow equalizing circuit 13 generates is by output isolated location
123 isolation, voltage signal Vs will not be transferred to signal amplification unit 122.

To voltage comparison unit 125, and the voltage signal Vc ' generated for isolation voltage comparing unit 125, i.e. voltage signal Vc ' quilts
It inputs isolated location 124 to be isolated, without being transferred to flow equalizing circuit 13.
Voltage comparison unit 125 is used for receiving voltage signal Ve ' and voltage signal Vs, utilizes voltage signal Ve ' and voltage
Signal Vs obtains voltage signal Vc ', by voltage signal Vc ' outputs to regulation unit 126.Wherein, if voltage signal Ve ' is big
In voltage signal Vs, this voltage signal Vc ' exported can be made to be less than the voltage signal Vc ' of last time output.If voltage signal
Ve ' is less than voltage signal Vs, this voltage signal Vc ' exported can be made to be more than the voltage signal Vc ' of last time output.If voltage
Signal Ve ' is equal to voltage signal Vs, this voltage signal Vc ' exported can be made to be equal to the voltage signal Vc ' of last time output.
Regulation unit 126 is used for receiving voltage signal Vc ', and second power supply module 12 is controlled using voltage signal Vc '
Output voltage, such as generate the control signal Voc ' of pulsewidth modulation using voltage signal Vc ', control signal Voc ' is for adjusting the
The output voltage of two power modules 12.When the voltage signal Vc ' of this input is more than the voltage signal Vc ' of last time input, then
The control signal Voc ' of this output is more than the control signal Voc ' of last time output, and control signal Voc ' is for generating more than last time
Big PWM pulsewidths, to improve the output voltage of second power supply module 12, load current Ib will become larger.When the electricity of this input
When signal Vc ' being pressed to be less than the voltage signal Vc ' of last time input, then the control signal Voc ' of this output is less than the control of last time output
Signal Voc ' processed, control signal Voc ' is for generating than last time more smaller PWM pulsewidths, to reduce the defeated of second power supply module 12
Go out voltage, load current Ib will become smaller.When the voltage signal Vc ' of this input is equal to the voltage signal Vc ' of last time input, then
The control signal Voc ' of this output is equal to the control signal Voc ' of last time output, and control signal Voc ' is for generating and last time phase
Same PWM pulsewidths so that the output voltage of the first power module 11 remains unchanged, and load current Ib is also remained unchanged.
Based on above structure, the load current Ia of the first power module 11 can be made with the load electricity of second power supply module 12
The current ratio for flowing Ib is 1：M, i.e. the load current Ia of the load current Ib of second power supply module 12 and the first power module 11
Current ratio be m：1.It should be noted that the acquisition of proportion adjustment unit 111 is second power supply module 12 and the first power supply
Current ratio Coefficient m between module 11：1 (being subsequently known as m), be not between the first power module 11 and second power supply module 12
Current ratio coefficient 1：m.
Shown in Figure 6, flow equalizing circuit 13 (such as current equalizing bus bar) is used to carry out all voltage signals itself received equal
Stream process, obtains voltage signal Vs, under original state, it is assumed that load current Ia is identical as load current Ib, current ratio Coefficient m
It is 3, then the voltage signal Vi of the first power module 11 and the voltage signal Vi ' of second power supply module 12 can be identical, the first electricity
The voltage signal Ve of source module 11 can be identical with the voltage signal Ve ' of second power supply module 12, the electricity of the first power module 11
Press signal Vk=3*Ve.
Flow equalizing circuit 13 is after receiving voltage signal Vk and voltage signal Ve ', to voltage signal Vk and voltage signal Ve '
Equal stream process is carried out, voltage signal Vs=(3*Ve+Ve ')/2=2Ve is obtained.Since Vk is more than Vs, Vc is reduced, and Voc is used
In generating than last time more smaller PWM pulsewidths, the output voltage of the first power module 11 is reduced, load current Ia will become smaller.Due to
Ve ' is less than Vs, and therefore, Vc ' is improved, and Voc ' is used to generate the PWM pulsewidths than last time bigger, improves the defeated of second power supply module 12
Go out voltage, load current Ib will become larger.Clearly as the load current Ia of original state is identical as load current Ib, load electricity
Stream Ia becomes smaller, and load current Ib becomes larger, then load current Ia is different from load current Ib.
After constantly repeating above-mentioned adjustment process, due to the stream effect of flow equalizing circuit 13 so that the first power module 11
Voltage signal Vk it is eventually identical as the voltage signal Ve ' of second power supply module 12, due to Vk=3*Ve, Ve '=3*
Ve, moreover, Vi '=3*Vi, Ib=3*Ia.That is, the electricity of load current Ib and first of second power supply module 12 can be made
The current ratio of the load current Ia of source module 11 is 3.
