Abstract
An electronic circuit is for optimizing or reducing switching losses in current-driven power devices and includes a switching power device connected to an electric load. The power devices has at least one control terminal arranged to receive a predetermined drive current value produced by a first current generator. The control terminal also receives an additional drive current portion produced by a second independent current generator. Advantageously, the electronic circuit includes a control circuit for controlling a switch connected between the second current generator and the control terminal of the switching power device during the turn-on and turn-off phases of the power device.
