In this paper, a new series resonant inverter which can be constructed simply using natural commutation switches is proposed. The proposed inverter can be operated on full four quadrant with almost unity power factor. It is also shown that the proposed inverter does not require damping circuit or special control loop for stabilization and solved the inherent problem in series resonant inverter such as oscillation. Simulation results also show that the output current is well regulated to the command value without scarificing the advantages.
