Circuit arrangement for the operation of a switching transistor

摘要

The circuit arrangement comprises a driver stage and a control circuit coupled to the control input of a switching transistor. The driver stage provides a switching voltage for the operation of the switching transistor, and the control circuit provides a shaping of the switching voltage in the sense of delaying the switching through of the switching transistor. The control circuit comprises in particular a control transistor, which is coupled a control input via a high pass filter to the output of the driver stage and with an current input to the control input of the switching transistor. The switching transistor is for example a MOSFET being used for switching on and off a capacitive load.
