Method and arrangement for controlling semiconductor component

摘要

A method of controlling a semiconductor component and a control arrangement, which component (1) comprises a voltage controlled gate. The method comprises the steps of determining and storing, prior to use of the semiconductor component (1), reference values of a gate voltage to be given to the gate of the semiconductor component during a change of operating states, and providing a pulse width modulated voltage from a driver circuit (C1) to a resistor (Rg) connected to the gate of the semiconductor component (1) according to the stored reference values of the gate voltage when a change in operating states of the semiconductor component (1) is desired.
