ABSTRACT:
A driver circuit for a high voltage switching power transistor has a first stage connected to the power transistor control terminal for turning the power transistor on and off, and a second stage connected to the power transistor control terminal acting as a current sink for capacitive current due to the transistor capacitances. The second stage is arranged to turn on when the power transistor control terminal voltage falls below a turn-on value and to be turned off when that voltage rises above a turn-on value. A driver circuit for a high voltage half-bridge switching power circuit, having two such power transistors connected in series, has similar upper and lower driver circuits and a level shifting circuit for providing control pulses to the upper driving circuit.
