Abstract
A switching circuit includes two power transistors () connected in series and a circuit () for exciting each transistor suitable for simultaneously switching the two transistors. The circuit includes elements () for generating a corrective current (δi) for controlling a corrected-control transistor () among the two transistors () according to the difference in temporal variation of the voltage at the conduction terminals of the two series-connected transistors (), and elements () for applying the current to the gate electrode of the corrected-control transistor ().
