Abstract

Reduced component count (RCC) inverters are being explored extensively due to better reliability and level to switch ratio. In this paper, analysis is performed on a RCC multilevel inverter that can generate 9 levels on symmetric mode and 17 levels on the asymmetric mode. The analysis is done with fundamental PWM techniques like Half Height (HH) method, Equal-Phase (EP) method, Half Equal Phase (HEP) method and Feed-Forward (FF) method. The performance is analysed through MATLAB based simulations and the comparison on the harmonic distortion is presented.

基于基频PWM方案的17电平非对称多电平逆变器

由于具有更好的可靠性和开关电平比，减少组件计数(RCC)逆变器正在被广泛探索。本文对一种在对称模式下可产生9个电平，在非对称模式下可产生17个电平的RCC多电平逆变器进行了分析。分析使用基本的PWM技术，如半高(HH)方法，等相(EP)方法，半等相(HEP)方法和前馈(FF)方法。通过MATLAB仿真对其性能进行了分析，并对谐波失真进行了比较。
