A novel flying-capacitor dual buck three-level inverter

A novel flying-capacitor dual buck three-level inverter(FCDBTLI) was presented in this paper. It was a kind of flying-capacitor inverter, which was based on the main circuit of dual buck inverter. The topology cherished the merits of dual buck inverter, such as no shoot-through problem, no body diode reverse-recovery problem. The switches array of the inverter is flexible which realizes voltage balancing of the flying capacitors through logical controlling. The validity of the proposed inverter is verified by computer-aided simulation and experimental result.
