一种由三分频PWM波到方波转换的方法

A Method for Pulse Dropping in the Change from a PWM Waveform to a Square Wave

本文介绍了一种新的由PWM波转换到方波的方法,理论分析和实验证明,新的转换方法比传统的转换方法有明显的优越性,采用新的转换方法可以使转换期间逆变器输出端的电压冲击减小80%～90%。

A new method for pulse dropping in the change from a PWM waveform to a square wave is proposed.It is shown that the traditional method of pulse dropping is unsatisfactory and a new method produces much smaller step changes in the inverter output voltage.
