Abstract
The invention relates to a gate control deviceof a power semiconductor componentof the IGBT type. A ramp generator circuitdelivers a reference gate voltage at its output. A stage for the current amplification of the said reference voltage delivers a gate current to the IGBT component, this amplification stage comprising an ignition circuitand a rapid extinction circuitA slow extinction circuitis connected between the gate G of the IGBT component and the output of the generator circuit. A circuitfor the detection of a collector-emitter voltage of the component is connected to a feedback circuitdelivering a feedback signalthat acts on the rapid extinction circuitand on the outputof the generator circuit.
