ABSTRACT:
The invention relates to a control circuit for a semiconductor switch, comprising a transformer coupling (T1, T2) for generating AC voltage signals including both control energy and control information, a rectification coupling (DB1, DB2) for rectifying the AC voltage signals generated by the transformer coupling (T1, T2) for generating DC voltage levels (U1, U2, U3) appropriate for turning on and turning off a semiconductor switch (SW1), a first resistor (R2) connected at its first end to a driving electrode of the semiconductor switch (SW1), a second resistor (R1) connected between the driving electrode and the emitter or source electrode of the semiconductor switch, and a booster semiconductor switch (V1) provided between the driving electrode of the semiconductor switch (SW1) and an DC voltage output (U3) generated by the rectification coupling and intended for turning off the semiconductor switch, the driving electrode of the booster semiconductor (V1) being connected to a DC voltage output (U2) generated by the rectification coupling and intended for controlling the booster semiconductor. The control circuit further comprises a zener diode (V2) connected between a second end of the first resistor (R2) and a DC output (U1) generated by the rectification coupling and intended for turning on the semiconductor switch (SW1) and a diode (V4) connected in a forward direction between the turn-off voltage output (U3) of the rectification coupling and the emitter or source electrode of the semiconductor switch (SW1).
