Abstract

The invention discloses a charging power supply test load and system, and belongs to the technical field of power supply test loads. The charging power supply test load comprises an energy storage capacitor which is connected with the output end of a charging power supply in parallel, and a resistive discharge loop and an inductive discharge loop which are connected with the energy storage capacitor in parallel. The resistive discharge loop and the inductive discharge loop are matched to simulate the process that the energy storage capacitor is discharged to zero and then is recharged, various load characteristics of the charging power supply are accurately simulated, and back voltage and residual voltage adjustment of the energy storage capacitor is realized by controlling the working time of the resistive discharge loop. Therefore, various working condition parameters of the charging power supply are truly restored.

Description

technical field [0001] The invention relates to the technical field of power supply test loads, in particular to a charging power supply test load and a system. Background technique [0002] The pulse charging power supply (hereinafter referred to as the charging power supply) used for charging the energy storage capacitor of the pulse power system generally performs charging work at a certain repetition frequency. In a single working cycle, the charging power supply first charges the energy storage capacitor, and then stores the energy The capacitor discharges the load for a short period of time before entering the next duty cycle. The load will release all the energy of the capacitor in a very short time. Since the load is generally inductive, part of the energy will be sent back after the discharge is completed. In practical applications, this part of energy will be recovered to the energy storage capacitor through the energy recovery circuit, so a cycle ends. After that...
