This study proposes a new topology for multilevel inverters based on switched‐capacitor structure. The proposed topology uses capacitor charged/discharged characteristic to boost the output voltage without employing magnetic elements. The proposed circuit configuration has fewer components, including switches, voltage sources, and capacitors comparing with the conventional similar topologies. A phase disposition pulse‐width modulation method is used to enhance the output waveform quality of the proposed inverter. Nine‐level and 17‐level configurations are simulated. To verify the operating principle, the experimental results for a nine‐level inverter topology are presented.
