Switching Mode

A novel switching mode power supply (SMPS) with input/output isolation is presented, which compounds the three-phase power factor corrector (PFC) with a full bridge converter in a single-stage. It solves the problem of over-voltage on the DC link due to pseudo-phase-shifting control (PPSC) mode. Its operating principle and critical parameters are analyzed. Experiment results of an isolated 10 Kw prototype show that the power factor of the system is above 0.99 and the soft-switching mode reduces most of the EMI.
