In the given paper the power losses of bi-directional semiconductor switches are evaluated in the context of laboration of an integrated matrix AC drive where such switches are used. Safe operation of the switches of a converter is extremely important factor of its successful operation of in whole. This, amongst other, assumes successful thermal design of the converter. The thermal design of matrix converters, especially integrated, is complicated due to the variety of their configurations, harder cooling conditions etc. For this reason the initial simulation of the losses through simulation seems helpful. This, however, requires an adequate model of the switches. In this paper the calculated, simulated and experimentally measured losses of the switches are compared and conclusions regarding the utilized model are made.
