Abstract
The invention concerns a method for controlling a switching assembly comprising a plurality of transistors connected in parallel, having a linear operating mode, a closed-switch operating mode and an off operating mode including a first operating phase during which a current flows from a source terminal to a drain terminal and a second operating phase during which no current flows. The method includes the following successive steps; (a) controlling the switching assembly in closed-switch mode during part of the first phase; (b) controlling the switching assembly in linear mode; (c) controlling the assembly in off mode during part of the second phase.
