Switched-capacitor-based multilevel inverters have been gaining increasing attention in recent years in view of their voltage-boosting

capability and capacitor selfbalancing properties. However, the existing topologies which comprises a frontend switched-capacitor

cells and a backend H-bridge result in longer discharging duration in some of their switched-capacitors. In addition, the adoption of

backend H-bridge introduces common mode voltage and necessitates multiple dc sources for voltage level extension. To resolve

these problems, this paper proposes a novel topology comprises a T-type inverter and ncascaded switched-capacitor cells. It requires

only a single dc source and it manages to mitigate the common mode voltage by connecting the neutral of ac output to the

midpoint of dc-link. All switched-capacitors in the proposed topology are ensured to be charged for at least half of the fundamental

period to alleviate  the capacitor voltage ripples and current spikes. The operation of the proposed topology is analyzed and

experimental results are presented for validation.
