Abstract A flyback grid-connected inverter with polar inversion bridge is studied in this paper. The circuit topology consists of a flyback DC converter and a polar inversion bridge cascade. The key contents of circuit topology, control strategy, working mode and steady state relationship are analyzed in depth. A 500VA 80~110V DC/220V 50Hz AC inverter prototype is designed and developed. It has the advantages of simple structure, low cost, high conversion efficiency and high output waveform quality. The feasibility and advancement of the circuit topology and control strategy are verified.
