Abstract
The utility model discloses a kind of surge current test circuit, including conversion module, control module and rectification filter module;Conversion module includes rectifier bridge BD1, electrolytic capacitor EC1, electrolytic capacitor EC2 and electrolytic capacitor EC3, to generate and accumulate surge current;Control module includes the switch SW1 and thermistor RC1 in series, to control release surge current;Rectification filter module includes filter S1, rectifier bridge BD2 and electrolytic capacitor EC4, to output after surge current rectification filtering. Thus, based on multiple electrolytic capacitor accumulation surge current, release opportunity is flexibly selected by switch, and different parameters of surge current can be obtained by adjusting thermistor specification, adapt to the surge current test demand of each type driving power supply or electrical equipment, wide range of adaptation, simple architecture.
