Abstract
This paper addresses various oscillation suppression methods in the AC-AC cycloconverter stage of a high frequency link inverter. Such oscillations occur after the natural commutation of the switches due to parasitic parameters of the converter circuit. A mathematic analysis of the resonance process in the cycloconverter stage is presented, followed by a comparative analysis of different snubber circuits that allow to minimize the effect of oscillations. The theoretical analysis is verified with software models and experimental prototype of 1 kW DC-AC converter.
