초록
PWM technique is widely applied to the control of AC machines. In this paper a new PWM technique for real-time implementation of variable-frequency sinusoidal PWM is introduced. In the proposed algorithm, a low pass filter is used and the switching state is so determined as to minimize the difference between the reference wave and the output of the filter.
