一种融合于驱动的电动汽车车载充电器
An Integrated On-Board Charger Mixed with Driver for Battery Electric Vehicle
摘要
Abstract
On-board charger breaks through the limitations of electric vehicles on the number and distribution of charging piles. This paper proposed a charging process of battery that utilizes the driving circuit of electric vehicle and the winding inductance of motor. The front-stage is a single-phase PWM voltage source converter(VSC), an AC supply is converted into a smooth DC power so as to reduce the current harmonics of grid and achieve PFC. In the back-stage, the DC-DC converter provides a maximum current constant voltage charging process of a predetermined value. Double-closed loop control of both front and back stages and feedforward control are adopted to better achieve the harmonic compensation of the power grid and current compensation of the load. The simulation results prove the validity of the proposed algorithm and the feasibility of the system.关键词
