Common-Ground (CG)-type multilevel inverters exhibit some interesting features in removing the concern of ground leakage current and improving the overall efficiency of the system within a single power processing stage. In this paper, a new reduced-switch count five-level (5L)-CG-based inverter is proposed, which offers a step-up voltage boosting property and can be extended to the three-phase systems whilst maintaining its CG-feature. The circuit descriptions, comparative study and the relevant measurement results for both the single and three-phase systems are presented to verify the feasibility of the proposed topology.
