ABSTRACT:
A circuit arrangement for protecting an electronic converter against overloads includes:a low impedance path selectively activatable to prevent ignition of the electronic converter, the low impedance path including an electronic switch,a control capacitor whose charge voltage controls the electronic switch, whereby the electronic switch is activated to prevent ignition of the electronic converter when the charge voltage of the control capacitor is above a given threshold,a first generator for loading the control capacitor, the first generator activatable in the presence of a first overload condition of the electronic converter, anda second generator for further loading the control capacitor, the second generator activatable in the presence of a second overload condition of the electronic converter, the second overload condition being heavier than the first overload condition.
