This paper proposes a novel three-phase rectifier which combines the benefits of diode bridge and PWM rectifier with high efficiency and low THD, making it suitable for high power DC fast charging applications. It targets at achieving high efficiency and control simplicity compared to conventional PWM type rectifier. The operation principle, current compensation method at voltage zero-crossing point and power loss analysis are presented and analyzed. Besides, simulations were performed in Matlab/Simulink and a 60kW prototype using IGBT modules and fast recovery diode bridge rectifier was built and tested. The experiment results manifest the merits of proposed three-phase rectifier with 99.5% peak efficiency and 9.2% THD.
