In this study, a structure of single‐phase seven‐level boost DC‐link cascaded multilevel inverter (BDCLCMLI) is proposed. It consists of boost converter, DC‐link module and H‐bridge inverter. Compared with conventional CMLI and two level H‐bridge inverter configurations, the proposed system results in reduction of voltage stress across the inverter switches, reduced power switches, DC source count and gate drive requirements. DC‐link switching is achieved by multicarrier sinusoidal pulse‐width modulation technique which results in improved quality of obtained output AC power. Reduction in DC source and switch count makes the system more cost effective. A simulation and prototype model of seven‐level BDCLCMLI system is developed and its performance is analysed for various operating conditions.
