The paper deals with switching power losses of DC-DC step-down converters supplying electrical machines. Due to a wide range of the load current, converter change the transistor duty factors from 0 to 100%. Since conductive losses are strictly connected with transistor parameters, duty factor and transistor currents, switching losses are the only part of losses that can be reduced, especially for small duty factors. The paper discusses two methods of reducing switching losses, the first one with energy recovery snubber and the second with SiC diode connected anti-paralell with the load.
