ABSTRACT:
A voltage-controlled transistor drive circuit includes a gate-voltage generating circuit for outputting on and off gate signal voltages in response to an input signal, switching a voltage-controlled transistor by applying the gate voltage to the gate of the voltage-controlled transistor; and a current limiting circuit limiting current flowing from the gate of the voltage-controlled transistor to the gate-voltage generating circuit when the gate-voltage generating circuit outputs an off gate signal voltage.
