Abstract

An improved PWM inverter waveform synthesis technique for harmonic control in delta modulation (DM) process is presented. Filtering approach is incorporated in the DM technique to reduce harmonics of lower frequencies and suppress the unwanted subharmonics. Analytical method is described to determine the performance of multistage delta modulated inverter and the results are substantiated by experimental verification.

一种用于逆变器运行的最佳增量调制策略
提出了一种用于增量调制(DM)过程谐波控制的改进PWM逆变器波形合成技术。在DM技术中加入滤波方法,以降低低频谐波和抑制不需要的次谐波。介绍了多级增量调制逆变器性能的分析方法,并通过实验验证了分析结果。
