Abstract
In power switches, conductive coupling of the control signal inputs to the power switching stage, and to the load to be switched, can result in impairment of control function. Moveover these power switches known in the art, have the disadvantage that the drive circuit and power switching stage must lie at the same potential. An improved self protecting power switch includes a first drive unit and a second drive circuit that are connected together via a pulse transformer. The first drive unit generates successive pulse trains in response to a control signal. A second drive unit regenerates square wave signals for the control of the power switching stage.
