Problems solved by technology

[0004] However, in the process of realizing the present invention, the inventor found that the defects of the prior art are: the existing aging power supply system is disturbed by the mains power grid, and an isolation transformer needs to be installed. Therefore, the approval of the power supply department is required, and the cost is increased; and, The loading power of the existing power aging system is fixed, which cannot meet the needs of the tested unit; in addition, the efficiency of feedback is low, which increases energy consumption

Embodiment 1

[0032] An embodiment of the present invention provides a power aging system, such as figure 2 As shown, the power aging system includes: a system balance supply unit 201, a regenerative load unit 202 and a DC conversion AC unit 203; wherein,

[0033] The system balance supply unit 201 is connected to the mains and output to the high-voltage DC bus, which is used to generate the DC power required for the constant current balance of the power aging system; the system balance supply unit 201 outputs a fixed voltage, and the power supply is aged by increasing or decreasing the output current The system maintains a constant current balance;

[0034] The regenerative load unit 202 is connected to the unit under test 200, and is connected in parallel with the system balance supply unit 201, and is boosted and output to the high-voltage DC bus for converting the low-voltage direct current output by the unit under test 200 into a high-voltage direct current; the regenerative load unit...

Embodiment 2

[0045] An embodiment of the present invention provides a power aging system, such as image 3 As shown, the power aging system includes: a system balance supply unit 301, a regenerative load unit 302, and a DC conversion AC unit 303; as described in Embodiment 1, details will not be repeated here.

[0046] Such as image 3 As shown, the power aging system may further include: a switching unit 304;

[0047] One end of the switching unit 304 is connected to the unit under test 300 , and the other end is connected to the mains or the regenerative AC bus for switching through the switch so that the mains or the regenerative AC bus provides the required AC power for the unit under test 300 .

[0048] Therefore, the switching unit 304 can connect the input end of the unit under test to the shared energy source (System Share Power) of the utility power generation system, or, be connected to the regenerative energy source fed back by the regenerative AC bus; therefore, the power cons...

Embodiment 3

[0082] The power aging system of this embodiment is basically as described in Embodiment 2, and will not be repeated here. The main difference from Embodiment 2 is that, except that the function of sampling analog signals such as current and voltage and converting them to AC / DC is implemented by hardware, other functions of the control unit are realized by software function modules, and the host computer Run each software function module to realize the online control of the system balance supply unit, regenerative load unit, DC conversion AC unit and switching unit; it is also possible to modify and set the system through the man-machine dialogue window of the host computer according to different tested units Each control parameter of the balance supply unit, the regenerative load unit, the DC conversion AC unit, the balance determination unit and the signal sending unit. Therefore, the operation of the system is more intuitive, the adaptability is stronger, and it can be appl...

Abstract

A power supply aging system and a load balance control method. The power supply aging system includes: a system share supply unit (201) for producing a DC voltage for the need of the system constant current balance, a renewable load unit (202) for converting a low DC voltage outputted by a unit under test (200) to a high DC voltage, a DC to AC converting unit (203) for converting the high DC voltage to the AC voltage needed by the unit under test. The AC voltage is transmitted to the unit under test through a renewable AC bus. The system does not need any isolation transformer or the authorization from power supplying enterprises. The system can balance the DC load sharing, reduce the cost, improve the efficiency of electrical energy feedback and reduce the energy waste.

Description

technical field [0001] The invention relates to the technical field of power electronics, in particular to a power aging system and a load balancing control method. Background technique [0002] In order to achieve high reliability, electronic products usually need to undergo a full-power aging process before leaving the factory. Generally, the aging system uses resistance as the power load, and the electric energy is converted into heat energy and wasted; moreover, in order to control the indoor temperature, a large amount of exhaust is required. The air system vents heat outside, warming the environment. [0003] At present, there have been power aging methods and systems for recycling energy. By feeding back the aging energy, energy loss and heat emission can be reduced. Such as figure 1 as shown, figure 1 It is an example diagram of a power aging system in the prior art, in figure 1 Among them, the unit under test (UUT, Unit Under Test) outputs DC to DC conversion AC...
