Abstract (en)
[origin: FR2815790A1] There is a transformer (4) with a primary winding (5) is connected in a series with an interrupter (6), e.g. FET, of voltage feeder. There is a secondary winding (7), which is associated with a capacitor (C2), and which supplies continuous low voltage. There is an self-oscillating control circuit for the interrupter. It comprises a detector (17) to detect auxiliary magnetization winding (8) of the transformer in order to open the interrupter when the current has reached a predetermined point. There are means to make the predetermined point variable in function with respect to the voltage at the auxiliary terminals
