Abstract

This paper proposes Switched coupled inductor (SCL) based quasi-Z- Source cascaded multilevelinverter (qZS-CMI), (SCL qZS-CMI) using nearest level modulation (NLM) technique in thispaper. The proposed inverter introduces appealing advantages over conventional qZS-CMI suchas lower component voltage stress, improved output power quality and efficiency. Bothsimulation and experimental verification have been carried out for SCL qZS-CMI with a powerrating of 250W to validate the above claims.
