Abstract: The design method of a drive system was introduced based on DSP TMS320F2812 in electric vehicle (EV) application. The hardware mainly included inverter and its drive circuit, interfaces of sensors, signal processing circuit,and a simple current limiting protection was presented. And the problem of current sampling was stressed in the software. The influence of different PWM control for torque was studied. The research shows that EV runs with safety and realiability, and the design effectively reduces costs.
Key words: drive system of electric vehicle; digital signal processor (DSP); current limiting protection; current sampling
