Abstract

This paper is a study of Multilevel Sinusoidal Pulse Width Modulation (MSPWM) methods; Phase Disposition (PD), Alternate Phase Opposition Disposition (APOD), Phase Opposition Disposition (POD) on a single phase Cascaded H-Bridge Multilevel Inverter. Various factors such as amplitude modulation index (Ma), frequency modulation index (Mf), phase angle between carrier and reference modulating wave (Φ) have been considered for simulation. Variation in these factors and their effect on inverter performance is evaluated. Factors such as DC bus utilization, output r.m.s voltage, total harmonic distortion (%THD), dominant harmonic order, switching losses are evaluated based on simulation results.

级联h桥多电平逆变器的多电平正弦脉宽调制方法研究

本文研究了多电平正弦脉宽调制(MSPWM)方法;单相级联h桥多电平逆变器的相位配置(PD)，交替相位对抗配置(APOD)，相位对抗配置(POD)。各种因素，如调幅指数(Ma)，调频指数(Mf)，载波和参考调制波之间的相位角(Φ)已经考虑了模拟。评估了这些因素的变化及其对逆变器性能的影响。根据仿真结果对直流母线利用率、输出有效值电压、总谐波失真(%THD)、主导谐波阶数、开关损耗等因素进行了评价。
