Before going to the discussion on how to select a transformer, let us cover first some of the transformer basic fundamentals. Transformer is could be a low frequency like those used in 50Hz or 60Hz line. Transformer is could be a high frequency one like those used in switching mode power supplies. Transformer will transfer power from the primary to

IGBT has two types of losses. One is conduction and the other one is switching. Conduction loss is due to the voltage drop between collector and emitter times the collector current. On the other hand, switching losses is due to the dynamic parameters of the IGBT. If you are looking for an explanation on how to derive IGBT power losses,
