摘要
In three-phase power factor correction converter, there exists severe switching loss. A zero voltage switching three-phase boost rectifier was researched. It used only one auxiliary switch and could realize zero voltage switching for all the switches and suppressed the diode reverse recovery current. The soft switching condition was analyzed and the design guide was proposed. The conduction loss and switching loss of the rectifier was calculated and the control strategy of the rectifier under unbalanced grid voltage condition was designed. A DSP controlled 40 kW prototype was built to verify the theory.
