In order to improve the efficiency of single-phase full-bridge inverter with insulated gate bipolar transistor (IGBT) as switching devices
a energy-saving single-phase full-bridge zero-current switching resonant pole inverter is proposed. A set of auxiliary circuit is connected with parallel on each bridge arm. In the working process
both the main switches and the auxiliary switches can achieve zero-current soft-switching
which can eliminate the turn-off loss caused by the tail current of IGBT. The working process of the circuit is analyzed. The experimental results on the 2kW prototype show that the switching devices achieve zero-current soft-switching. Therefore
the topology can realize the energy-saving operation of the single-phase full-bridge inverter with IGBT as the switch devices.
