Abstract
The device () comprises an energy-storage transformer () having magnetically coupled primary and secondary windings (P and L, L, L); a primary circuit () connecting the power supply source to a ground (M), and comprising the primary winding (P) and a static main switch () connected in series; a secondary winding (S, S, S) designed to be connected to a load, and including the secondary winding (L, L, L); and voltage control means () for controlling the static main switch () and comprising a first static control switch () connecting a control terminal (A) of the static main switch () to ground (M). More particularly, the voltage control means () of the static main switch () include a second static control switch () connecting the control terminal (A) of the static main switch () to ground (M), closure of the first control switch () triggering closure of the second control switch (), and opening of the second control switch () being delayed relative to opening of the first control switch ().
