This paper proposes a new zero current switched, IGBT based cyclo-Inverter, capable of converting power at the main frequency to a higher frequency. An auxiliary switch along with an inductor is used to commutate the IGBT at zero current in order to decrease total internal losses and total harmonic distortion factor in the converter. The proposed converter is compared with the conventional cyclo-inverter and it has been demonstrated that the losses has been reduced approximately 50% by this new switching technique. A prototype of the converter is developed in the lab for verification of the results.
