| Abstract: | A 5kW DC switching power supply is developed with common IRFM 460 in parallel as the main switching component and a three level zero voltage switching PWM as the main circuit topology. A study was carried out on three-level circuit, MOS in parallel etc.. Experiment results show that the switching power supply circuit is simple, the parameter selection is reasonable and the reliability is high.
