A novel power converter for battery used in the Plug-in Hybrid Electric Vehicle (PHEV) is proposed, which could charge and discharge the battery effectively. The system is composed of two parts: a three phase full bridge PWM rectifier and a DC/DC converter. The PWM rectifier is utilized to rectify the three phase AC to DC voltage, which should be higher than the battery terminal voltage. The DC/DC converter is constructed by a buck-boost circuit, which is a buck circuit under charge mode and a boost circuit under discharge mode. The direct current control (DCC) algorithm is responsible for rectifying the AC output and diminishing the total harmonics distortion. The proportional-integral (PI) controller and bangbang controller is to control the charging current and voltage. The simulation and experiment results validate the effectiveness of proposed algorithm and the feasibility of system.
