Fig. 1 diagrammatically illustrates the schematic diagram of power module in accordance with an embodiment of the present disclosure.
As shown in figure 1, the power module 100 can include：DC converting unit 101, for the defeated of regulation power supply module

It should be noted that DC converting unit 101 (Direct Current-Direct Current converter units, letter
Referred to as DC-DC converter units) it is used to ensure that small-power power and large power supply can provide the enough work(in specification limit
Rate；First amplifying circuit 102, realizes the detection of electric current, and the electric current detected progress is scaling, forms the first amplification electricity
Stream (also referred to as this earth-current).In accordance with an embodiment of the present disclosure, the first amplifying circuit 102 is used for the output electricity of different capacity power supply
It is in same magnitude of voltage error range to press stability.
In accordance with an embodiment of the present disclosure, the same power-supply system of multiple power module parallel connection insertions is likely to occur following two feelings
Condition.
Situation one：
Because being pind down by the electric circuit signal of load balancing, the electric current exported by DC converting unit can not be matched, only
The small power supply of power can be turned off from system end, the power supply for making power larger works independently.
For convenience to the understanding of the embodiment of the present disclosure, below by with the power supply of two different capacities in same power-supply system
Exemplified by, it should be appreciated that, these descriptions are merely illustrative, and is not intended to limit the scope of the present disclosure.
Table 1 shows the proportionate relationship for flowing bus of different capacity power supply, and correlation technique is come for size according to the table
The power module design of different capacity flows bus.
For example, power supply 1 and the parallel operation of power supply 2, power supply 1 are consistent with the output voltage of power supply 2, it is to realize load in proportion
The essential characteristic of distribution, wherein, the power output capacity of power supply 1 is 500W, and the power output capacity of power supply 2 is 1000W, if
System output power capacity is 500W, then two power supplys should respectively undertake 250W or so power.
Table 1
According to the stream bus design scheme shown in table 1,500W power supply (1/2 carries) stream bus voltage in 250W is
2.5V；1000W power supply (1/4 carries) in 250W, flows bus at 1.0V or so (1.25V).
And actual conditions are, 500W can only be to match (being all about 2.5V ranks) with the electric current of 500W power supplys, could carry out
Compare, realization is flowed；1000W can only be to match (being all about 1V grades) with the electric current of 1000W power supplys, can just be compared, and realize
Flow.
Obviously, 2.5V (500W power supplys) and 1.0V (1000W power supplys), two voltage ranges are too wide in the gap, it is impossible to match, do not have
Method carries out signal comparison, thus can not realize automatic current equalizing.Now, the small power supply of power can only be turned off from system end, power is allowed
Larger power supply works independently.
Situation two：
Even if multiple parallel connection power supplies can realize that load is flowed, i.e., the load capacity of each power supply is identical, is also only capable of in power supply
The power output of system could realize the superfluous of power-supply system when being less than the peak power output of any power module in power-supply system
Complementary characteristic.
Table 2
Now, loading condition is changed to actual power number by percentage, realizes different electrical power under identical power output
Load stream bus is equal, as shown in table 2.
In other words, or the power module parallel operation scheme in correlation technique can not realize that the redundancy of power-supply system is special
Property, or it conditional can only realize the redundancy properties of power-supply system.In this case, if using above-mentioned power module 100,
The second amplifying circuit 103 being provided with can be by the first amplification electric current amplified by the first amplifying circuit 102 by predetermined ratio
Example is amplified output second and amplifies electric current, by the corresponding voltage of 104 pair of second amplification electric current of Load Balance Unit and bus electricity
The voltage difference feeding feedback unit 105 of pressure so that DC converting unit 101 adjusts output current so that the second amplification electric current pair
The voltage and the voltage of bus voltage answered reach equilibrium, and now the power module in power-supply system and other power modules are realized negative
Carry proportional assignment.It should be noted that aforementioned proportion can this power module and the capacity of other power module power outputs
Than.Distinguishingly, if the capacity of the power module power output in this power-supply system is identical, the ratio is 1: 1, realizes that load is equal
Stream.
It should be noted that the amplification electricity of DC converting unit 101, first in the power module that the embodiment of the present disclosure is provided
Road 102, the first amplifying circuit 103, Load Balance Unit 104 and feedback unit 105 can be with hardware and/or the shapes of software programming
Formula is realized, is not limited thereto.
Compared with correlation technique, the power module 100 that the embodiment of the present disclosure is provided can be by due to the second amplifying circuit 103
First amplification electric current of the first amplifying circuit 102 output zooms into the second amplification electric current by predetermined ratio, and second amplifies electric current
Corresponding voltage will remove to chase voltage in bus, finally the two is reached equilibrium.In other words, the second amplifying circuit 103 causes
The corresponding voltage of the second amplification electric current of the power module of the different capacity inserted in same system is finally balanced with bus voltage,
In the case where multiple power sources in parallel are powered, different electrical power realizes load proportional assignment.
Fig. 2 diagrammatically illustrates the schematic diagram of the power module according to another embodiment of the present disclosure.
As an alternative embodiment, as shown in Fig. 2 above-mentioned second amplifying circuit 103 can include：Compensating unit
1031, for obtaining and being calculated according to the first capacity information and the second capacity information to obtain predetermined ratio, wherein, second
Capacity information is the capacity information of the power output of other power modules；And amplifying unit 1032, for by predetermined ratio pair
First amplification electric current is amplified to obtain the second amplification electric current.
It should be noted that compensating unit 1031 is used in the initialization procedure when power supply is started shooting, power-supply system is gathered
The capability value of the power output of middle different electrical power module, and by the maximum current capacity in each power module collected, with this
It is the maximum power module of output current to assert power supply corresponding to this magnitude of current, and combine the capacity information of this power supply (can be with
Obtained from the control chip for being arranged on this power module, can also be from a memory cell for being provided separately within this power module
It is middle to obtain), the different information of this power supply and the power supply of peak power output is drawn, and different information is sent into amplifying unit 1032
In, error amplification is carried out, and error correction is carried out by equalizing circuit, different information can be this power supply and peak power output electricity
The Capacity Ratio of the power output in source
During initialization when all power supplys in insertion system are all started shooting, capacity of each power supply to oneself
The capacity of other power supplys with being obtained from another channel is compared, if the capacity of oneself power supply is not maximum, i.e., strong
System makes compensation circuit that the compensation rate of itself electric current is amplified, and backfeed loop is reduced the electric current output of this power supply in proportion.
So, the power supply of maximum capacity will undertake maximum current in initialization procedure, and the power supply of minimum capacity is first
It will undertake minimum current after beginningization, and this magnitude of current that power supply is undertaken on two is proportionate relationship by measure distributes.
For example, 1000W power supplys are powered with 500W power sources in parallel, when power output is 750W, 1000W power supply is in initialization
When just distribute to oneself 2/3 electric current, and 500W power distributions give oneself 1/3 electric current.
Vbus (Voltage Bus, referred to as bus-powered voltage) of the 1000W power supply in 750W*2/3=500W be
5*1/2=2.5V (is shown in Table 1).
500W power supply is in 750W*1/3=250W, for 500W, and Vbus voltages are 2.5V (being shown in Table 1).
The corresponding electricity of electric current in load bridging bus (also referred to as Load sharing bus) is drawn by maximum detection method
Pressure is 2.5V.
It can be seen that it (is to have certain mistake that the Vbus voltages 2.5V of Vbus (2.5V) and 1000W during 500W, which is more or less the same,
Difference), in an order of magnitude, realize and flow from the point of view of load balance circuit.
It should be noted that amplifying unit 1032, poor by the calculating of compensating unit 1031 for during initialization
Value performs amplification and corrected, so as to be adapted with the compensation rate of compensating unit 1031.Specifically, power module is according to compensating unit
1031 amplification coefficients obtained are simulated to power supply, and feed back to Load Balance Unit 104, make 104 pairs of Load Balance Unit
Current signal after amplification carries out load balancing regulation, feedback unit 105 is sent the feedback with Simulation scale-up current in proportion
Signal, adjusted by the offset of compensating unit 1031 output valve in output current, i.e. amplifying unit 1032 be two not
With the difference between current between capacity power source, this difference between current is used for the current differential in polishing compensating unit 1031, make equalizing circuit with
Electric current rice after compensation calculates and realizes current balance.
When power supply makes the electric current that it undertakes due to some unexpected factors (such as output voltage fluctuation) beyond dividing in proportion
During the principle matched somebody with somebody, amplifying unit 1032 carries out Linear Amplifer correction, is allowed to return to according to the error provided in compensating unit 1031
Come on the working current value of proportional assignment.
In the disclosed embodiments, the second amplifying circuit 103 includes compensating unit 1031 and amplifying unit 1032, can be with
Predetermined Current amplifier ratio is provided to the second amplifying circuit 103 so that the second amplifying circuit 103 reasonably can be put to first
The first amplification electric current that big circuit 102 is exported is amplified, and finally realizes the output current proportional assignment of different electrical power module.
That is the electric current of the first actual amplifying circuit 102 output and the electric current of the second amplifying circuit 103 output just form one
Proportionate relationship, this proportionate relationship causes load balance circuit " to take for " load balancing, and actual without equilibrium, realizes balanced
Be the analog signal analogue unit of amplification (come from current ratio), and actual electric current is not carried out equilibrium, but with
One proportionate relationship of scaling and analogue unit signal formation.That is, forming the premise of nominal load balancing
Under, actual current and the relation of the electric current composition amplification in load bridging bus.Also reformed into two power modules
Large power supply realizes the pro rate of load with small-power power.
