Based on the working conditions and development trend of operating mechanism of high-voltage circuit breaker, this paper presented a high-load adjustment rate of portable high-frequency switching power supply designed for high-voltage circuit breakers test. The main circuit topological structure is analysed in detail, which uses the fullbridge circuit and IGBTs (insulated gate bipolar transistor) as switches. The focus is on the EMI (electromagnetic interference) filter circuit and soft-start circuit. The PWM (pulse-width modulation) integrated chip TL494 is adopted to control the power supply. Test results showed that the design was reasonable and had reliable performance.
