Abstract: This paper main discusses the application of AVR--a new type of high-speed embedded micro-controller in the field of AC variable frequency speed regulation (VFSR) system, the designed method of hardware and software were given. The SPWM signal generated by Area Equivalent Principle solve the demands of control accuracy and real-time control. It was proved by analysis and simulative experiment that the proposed method is effective.
