Improved “K” type seven‐level switched capacitor inverter topology with Self‐voltage balancing
International Journal of Circuit Theory and Applications, 2020SummaryThis paper proposes an improved “K” type seven‐level switched capacitor inverter topology. The proposed topology consists of eight active switches, one floating capacitor, and two dc‐link capacitors. The floating capacitors are charged and discharged in each half‐cycle to maintain the capacitor voltage with the same value of the input voltage ...
