Description
Technical field
The present invention relates to power electronic product fields, and in particular to a kind of power-supply system.
Background technique
Usually there are two types of mode agings for the DC output power module of the prior art, and one is pass through power module output
Ohmic load or electronic load carry out aging, another is that power module output connects feedback load energy is fed back to power grid
Carry out aging.The energy of module is at high cost all by load consumption when connecting resistance load or electronic load aging, is generally adapted
Application few in module number, power is small.For communication power supply module, high-voltage direct module or high power D C/DC mould
For block, individual module power is larger, and multimode aging simultaneously is required when aging, generallys use the mode for connecing feedback load, such as
Shown in Fig. 1.But feedback load the problems such as there are at high cost, volume is big, input voltage range is limited.When similar communication power supply this
When needing to connect high pressure feedback load when the lower module of class output voltage and carrying out aging, the output of module must use concatenated side
The input voltage range that formula matches feedback load just can be carried out aging.
Usual AC/DC module also allows work under the conditions of DC input voitage, when module input is DC voltage, reason
Module input can be fed back to by the energy of upper module direct current output, module is completed from aging, and external power supply only needs to provide few
The module own loss energy of amount.In patent《Power-supply system》In, one kind is provided from aging techniques, is opened by power supply unit offer
Module output is fed back to module input after module work and carries out aging, as shown in Figure 2 by dynamic voltage.But there are three for the program
A major defect：First the disadvantage is that the output voltage of module not above the maximum input voltage that module allows.For some
The occasion of high voltage direct current output, such as single-phase charging module, maximum allowable DC input voitage is lower than 450V, and maximum output is electric
Pressure is 750V.It, cannot be straight by this way since output voltage is greater than input voltage when needing module to export 750V aging
Tap into row module aging.Second the disadvantage is that power module can be right according to input voltage, the output of output voltage limitation full power
For communication power supply module, it can only be boosted by output series system to reach the minimum input voltage requirement of module, and need
Total output voltage is controlled lower than module maximum input voltage, and the aging voltage for exporting series connection by module to match is different
Surely meet the input voltage range of the fully loaded output of module.If not being able to satisfy the voltage conditions of full power output, module can only drop
Power aging, and module aging usually requires that it carries out aging close to fully loaded.Third disadvantage is exactly the electricity in the ageing system
Source module works in current limliting state, it is necessary to control it by setup module current limliting point mode and export electric current, output voltage adjusts model
Enclose the stringent limitation that will receive input voltage range.And in ageing process, it is often desirable that module work is in constant pressure state, to meet
The aging requirement of module difference output voltage, different output current.

Row aging.It when power module device output voltage range differs too big with its input voltage range, needs to be connected switch S1, leads to
It crosses the suitable boosting of selection or load step-down modular device 300 carries out aging.
Wherein, power supply unit 100, any one in power module device 200 and load blocks device 300 both can be
Support the single-phase AC/DC module of direct current input, or the three-phase AC/DC module for supporting direct current input, can also be direct current
DC/DC module.When power supply unit 100, any one in power module device 200 and load blocks device 300 is single-phase AC/DC
When module application, Vin1 and Vin2 can be with the firewires and zero curve of order phase module；When power supply unit 100, power module device 200
When with any one in load blocks device 300 being three-phase AC/DC module, Vin1 and Vin2 connect any two fire of three-phase module
Line or a firewire and zero curve.
The output of power supply unit 100 and load blocks device 300 is just connected in parallel, negative to be connected in parallel, cannot be positive and negative
Intersect wiring.The output of power module device 200 is connected to the input of load blocks device 300, positive and negative to intersect wiring.
Power supply unit 100 is used as starting module, can be by external switch or internal communication mode come control module
Booting and shutdown, the aging requirement of repeated switching when realizing power module 200 aging of device.
