ABSTRACT:
A driving circuit for an insulated gate bipolar transistor (IGBT) which has a power source, a gate voltage input circuit which supplies the voltage to a gate terminal of IGBT, a detecting circuit for detecting a collector to emitter voltage of the IGBT and an adjusting circuit for lowering the control signal.
When an abnormality is detected by the detecting circuit, the adjusting circuit performs a dropping operation of the gate voltage of the IGBT immediately after the detection or after the passage of a predetermined time following the application of the ON signal to the gate.
