Analysis of the Harmonic Characteristics of the CPS-SPWM Output Voltage of Cascaded H-Bridge Converters Based on Irregular Sampling
摘要
Abstract
Based on the irregular sampling method,the harmonic characteristics of the CPS-SPWM output voltage of cascaded H-bridge multilevel converters are analyzed in this paper.Simulation and experimental results show that,on condition that the carrier wave frequency defined as ?c is much larger than the sinusoidal modulation wave frequency,the fundamental component of the CPS-SPWM output voltage will lag the modulation wave a quarter of carrier wave period.Additionally,the odd harmonic components mainly distribute near the even times the number of N?c,while the even harmonic components are eliminated.关键词
