A 17-Level Asymmetric Multilevel Inverter with Fundamental Frequency PWM Schemes

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.
