摘要
本文提出了用梯形脉宽调制（ＴＰＷＭ）降低逆变器谐波的一种新方法。在逆变器中，较正弦脉宽调制（ＳＰＷＭ）方法它体现优越的谐波控制性能。对梯形调制信号的三相ＰＷＭ逆变器输出波形从理论和实验两个方面作了研究。
This paper presents new technique for harmonic reduction in inverter using trapezoidal pulse width modulation (TPWM);In this inverter, it offers excellent harmoniccontrol in comparison with sinuoidal pulse width modulation(SPWM)technique. The out-put waveform of a three-phase PWM inverter for the trapezoidal modulation signal is investigated both theoretically and experimentally.
