Abstract:A novel flying-capacitor dual buck five-level inverter (FCDBFLI) is presented in this paper. It is a kind of flying-capacitor inverter , which is based on the main circuit of dual Buck inverter. The topology cherishes the merits of dual buck inverter, such as no shoot-through problem, no body diode reverse-recovery problem. The switches array of this inverter are flexible which enable to realize the balance state between the charging and discharging of the flying capacitors by logical control. Simulation and experiment verifiy the truth of those analyses.
