Abstract:
A combination comprising:a transistor having first and second electrodes defining the ends of its main conduction path and a control electrode for controlling the conductivity of its conduction path;means for connecting an inductive load to the first electrode of the transistor;means for connecting the second electrode of the transistor to a first point of reference potential;a circuit responsive to an input signal connected to the control electrode of the transistor for selectively turning it on and off; anda network connected between the first and control electrodes of the transistor comprising:(a) ""X"" PN junctions; where ""X"" is an integer greater than one; means connecting the ""X"" PN junctions in series between the first electrode and the control electrode of the transistor;(b) a bypass capacitor connected across the PN junctions electrically closest to the control electrode of the transistor; and(c) discharging means connected in series with said by-pass capacitor between said first point of reference potential and the first electrode of the transistor for providing a discharge path for the by-pass capacitor when the transistor is turned on.
