Abstract:
The invention relates to an electronic ballast presenting an input capacitor and comprising and step-up chopper for operating a load, for example a discharge lamp, on a phase control dimmer having an integrated or parasite inductance. In such a way, the voltage overshooting on the input capacitor are reduced by active charge or discharge thereof.
