Abstract: A drive circuit including a first transformer unit in connection with a pulse amplifier module and a second transformer unit in connection with a plurality of power semiconductor groups, each group containing one or more power devices. The first transformer unit includes at least one primary transformer configured to receive a current pulse at a primary winding from a current pulse generation module, the current pulse being reflected to a secondary winding. The second transformer unit includes a plurality of secondary transformers where each secondary transformer is configured to receive the current pulse at a primary winding thereof, the current pulse being reflected to a secondary winding coupled to a pulse receiver module. The first and second transformer units reduce parasitic coupling between the pulse receiver module and the control module.
