An improved single-phase asymmetrical multilevel inverter structure with reduced number of switches and higher power quality

This brief proposes an improved single-phase multilevel inverter with asymmetrical structure, consisting of ten unidirectional SiC MOSFET switches and four direct current (DC) voltage sources to produce a twenty-one voltage levels alternating current (AC). The main advantages of the proposed multile...
