A current regulated pulse width modulation method with new series resonant inverter

A 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 shown that the inverter does not require a damping circuit or special control loop for stabilization, and it solves the inherent oscillation problem in series resonant inverters. Simulation results also show that the output current is well regulated to the command value without sacrificing the advantages.<>
