      An on-board charger based on TMS320F28020 DSP chip was developed to charge electric vehicles safely and automatically. A half-bridge DC/DC topological structure was adopted, and a transformer isolation drive circuit was designed, which was suitable for high-frequency pulses. The charging strategy was realized through software programming, and the hardware structure of the charger circuit and the flow chart of software program were introduced in detail. Moreover, tests were carried out an experimental prototype, and the results proved the feasibility of the design of system software and hardware.
