Digital Charger Powersource for Electric Vehicle Based on TMS320LF2407A

The significance of researching on digital charger was simply introduced firstly. The theory of digital charger main circuit was particularly analyzed composed of shift-phase full bridge inverter and secondary rectifier. Control system circuit based on the TMS320LF2407A, software and digital PID controller was particularly designed. Outcome of the experiment and technical parameter were given. The charger has good output characteristic with soft switching, digital control and could meet the need of complex charging method of different kinds of battery.
