Title:
SWITCHING POWER SUPPLY AGING TEST SYSTEM AND AGING TEST METHOD
Document Type and Number:
WIPO Patent Application WO/2019/028817
Kind Code:
A1
Abstract:
A switching power supply aging test system and an aging test method. The system comprises a direct current power supply (101), a switching power supply being tested (102), and an energy feedback load (103). An input end of the direct current power supply (101) is electrically connected to the mains electricity. An output end of the direct current power supply (101) is electrically connected to an input end of the energy feedback load (103). The input end and an output end of the energy feedback load (103) also are electrically connected respectively to an output end and an input end of the switching power supply being tested (102). The direct current power supply (101) provides the energy feedback load (103) with a first input direct current power supply. The energy feedback load (103) provides the switching power supply being tested (102) with a second input power supply. The direct current power supply (101) also is used for providing for the power loss of the switching power supply test system in an aging test process. A third output direct current power supply and the first input direct current power supply outputted by the switching power supply being tested (102) jointly provide the energy feedback load (103) with a power supply input. The method facilitates a reduction in the power loss of the switching power supply aging test system and increases the energy recovery and reuse rate of the aging test system.
