Abstract :
This paper suggests the Li-Battery fast charge system based on DC link. That is composed of 3phase PWM converter, PV boost converter and isolated full-bridge converter. This paper studies power control scheme of the entire system and how the rapid charging of the battery. The proposed system is supplied the power from not only grid by current control of the 3phase PWM converter but also MPPT(Maximum Power Point Tracking) control of PV system, and rapidly charge the Li-battery by CVCC method (constant voltage/constant current) of the isolated full bridge converter.
