A Switched Capacitor based Multilevel Inverter using Stepped Waveform Technique

Abstract: It is pretty preferable to adapt high frequency (HF) transmission rather than low frequency AC power distribution systems (PDS).Because HF inverter acts as source side in HFAC PDS. A new switched capacitor (SC) based multilevel inverter (MLI) is proposed in this paper which is designed by SC at frontend and H-Bridge backend. SC is connected in series and in parallel to increase the number of voltage levels. With increase in number of voltage levels total harmonic distortion (THD) can be reduced. A stepped waveform method is proposed in this paper to determine the switching angles. The circuit topology, stepped waveform technique, operation, Fourier analysis, parameter determination and topology enhancement are examined. An experimental prototype with output frequency of 25 kHz is implemented to compare the results.
