Abstract :This paper proposes Switched coupled inductor insert ignore into journalissuearticles values(SCL); based quasi-Z- Source cascaded multilevel inverter insert ignore into journalissuearticles values(qZS-CMI);, insert ignore into journalissuearticles values(SCL qZS-CMI); using nearest level modulation insert ignore into journalissuearticles values(NLM); technique in this paper. The proposed inverter introduces appealing advantages over conventional qZS-CMI such as lower component voltage stress, improved output power quality and efficiency. Both simulation and experimental verification have been carried out for SCL qZS-CMI with a power rating of 250W to validate the above claims.
