A circuit for controlling two switches assembled in anti-parallel, comprising
in
series between two terminals of the anti-parallel assembly, two identical control
stages respectively dedicated to each switch and between which is interposed a
common impedance setting a phase angle for the turning-on of the switches, each
stage comprising: a controllable current source for providing a current to a control
electrode of the concerned switch; a capacitor for storing a supply voltage of
at least the current source; an element of activation/deactivation of a the current
source according to the voltage across the stage capacitor; and an assembly for
discharging the capacitor.
