Abstract: A new method, using AVR singlechip computer to produce SPWM waves and realize feedforward control, was proposed to accomplish full digital control of the inverter power supply. On the bases of analyzing the characteristics of the ATmega8 chip, the specific design of softwarehardware structure was given. The results of the simulation and the experiments show that the circuit of the system is simple, the control scheme is reasonable and feasible, and it has wide prospect in the future.
Key words: AVR singlechip computer; inverter; sine pulse width modulation (SPWM); feedforward control
