In order to realize a simple topology, high efficiency, high frequency, low voltage stress, easy to control soft switching three phase inverter, this paper introduces a novel resonant pole three phase inverter, which realized the zero-voltage switching of the main switches, zero-current switching of auxiliary switches and possesses the small power auxiliary circuit and full PWM capability. It avoids the bulk capacitor of the auxiliary resonant commutated pole inverter (ARCPI) and no center tap potential variation problem of ARCPI, unlike the delta or wye(Y) configured resonant snubber inverter, the inverter possesses the advantages of the decoupled resonation of each phase, it is easy to implement the various control schemes. The operation principle of one phase circuit has been analyzed and the equivalent circuits at different operation modes for both ZCS and ZVS operations are present. Simulation and experimental results are proposed to verify the theoretical analysis.
