In this paper, a new soft switching T-type three level inverter is proposed. The proposed new converter provides for main switches to turn on with Zero Voltage Transition (ZVT) and turn off with Zero Voltage Switching (ZVS) without any voltage or current stresses. Also, the proposed new converter provides Soft Switching (SS) for all semiconductors. Besides, Electro Magnetic Interference (EMI) noises are decreased by soft switching cell. The proposed converter has a low cost, ease of control and simple structure. The theoretical analysis of converter is clarified and the operating stages are given in detail. The simulation results of converter are obtained for 3.3 kW and 50 kHz by PSIM program. It is observed that the simulation results and theoretical analysis of converter are perfectly suitable with each other.
