This study offers an effective circuit arrangement of a multilevel inverter that can increase the number of output voltage levels with a lesser number of device count. A single dc‐source‐based seven‐level inverter (LI) with boosting capability is proposed in this study. The proposed inverter utilises eight switches, two diodes, two capacitors, one inductor and a single dc source to generate seven‐level boosted output. Usage of single dc source and boosting capability makes the proposed inverter suitable for electric vehicles as less number of series‐connected battery cells are required. Phase‐shifted pulse‐width modulation (PWM), a multi‐carrier‐based PWM technique is utilised to generate switching pulses for the proposed 7LI. Device count‐based comparative analysis of the proposed inverter with recent topologies is done. Viability and impact of the proposed inverter are analysed through simulation and are validated through laboratory prototype.
