车载充电机的硬件电路设计与实现

Powered by Vehicle energy storage battery and achieving the Zero emissions, the electric car has being become the mainstream in the development of new energy automobile .Therefore, it is necessary to develop our own intellectual proprietary car charger,which is cheaper and more efficient .The hardware circuit of the on-board charge consists of two parts of the main circuit and control circuits,Where the main circuit used for providing power supply for implementing AC/DC, DC/AC,AC/DC three conversions .The main circuit mainly complete input rectifier, full-bridge inverter output rectifier filter section and part of the design.The control circuit is mainly used for PFC control circuit, full-bridge inverter circuit drive control, and communicate with the battery management system, and the output current and voltage acquisition.This on_board charger achieve rated AC input to meet intelligent fast, efficient charging, there is a good self-protection requirements under mains, the self-diagnostic function and safety.?????
