Abstract
A switching circuit includes two power transistors (22, 24) connected in series and a circuit (26, 28) for exciting each transistor suitable for simultaneously switching the two transistors. The circuit includes elements (30) for generating a corrective current (δi) for controlling a corrected-control transistor (22) among the two transistors (22, 24) according to the difference in temporal variation of the voltage at the conduction terminals of the two series-connected transistors (22, 24), and elements (37) for applying the current to the gate electrode of the corrected-control transistor (22).
