Abstract

The invention discloses an aging test system for switch power supplies. The aging test system comprises a circuit breaker connected with a mains supply, at least one group of test arrays connected with the circuit breaker and an inversion feedback unit connected with both the test arrays and the mains supply, wherein the test arrays comprise at least one group of switch power supply combination units; each switch power supply combination unit comprises a plurality of switch power supplies; the input ends of the multiple switch power supplies are connected in parallel to be the input end of the corresponding switch power supply combination unit; the output ends of the switch power supplies are connected in series to be the output end of the corresponding switch power supply combination unit. Therefore, one test array is divided into a plurality of switch power supply combination units to facilitate control, and the number of compensation units can be reduced; more importantly, the inversion feedback unit inverts energy of the test arrays, and feeds back the inverted energy to the mains supply to fulfill the aim of energy conservation.

Description

technical field [0001] The invention relates to the technical field of switching power supplies, in particular to an aging test system for switching power supplies. Background technique [0002] Aging test is a quality method for power supply, such as switching power supply product reliability screening and verification before leaving the factory. In order to eliminate the early failure of switching power supply products and the stability and reliability of the market, manufacturers of switching power supply products generally use resistance energy dissipation to conduct product aging tests. The resistance energy consumption method refers to connecting the switching power supply directly to the cement resistance for testing. This test method wastes energy due to the heat generated by the resistor itself. [0003] It can be seen that how to reduce the energy consumption of the aging test of the switching power supply is an urgent problem to be solved by those skilled in the...
