A new method of optimized PWM based on 8/spl times/C196MC

This paper introduces a method of waveform generation and pulse width calculation of OPWM (optimized pulse width modulation) based on the single-chip-computer 8/spl times/C196MC. The experimental results show that the proposed method is practicable and the output OPWM waveform of the inverter has better performance in comparison with normal SPWM mode.
