摘要：
This paper presents a novel technique of pulsewidth modulation (PmTM) wave control to minimize the surge voltage at the turn off of switching devices. Two kinds of sawtooth carriers with different hypotenuses are employed to obtain a PWM waveform with minimum surge voltage, where each sawtooth carrier appears alternately at every 60 degrees interval relative to the sinusoidal wave cycle, It is difficult to analyze the output waveforms because they are complicated. In order to obtain the analytical result, a frequency analysis approach using a switching function is proposed the results of which are verified experimentally.
