Abstract (en)

[origin: CA2605217A1] The invention relates to an electronic ballast presenting an input capacitor (C) and comprising and step-up chopper (LH, DH, SH, CH) for operating a load , for example a discharge lamp(CFL), on a phase control dimmer (DIM) having an integrated or parasite inductance (L). According to said invention, excessiv e voltage after connection with a phase control can be reduced by adjusting currents by means of the step-up chopper (LH, DH, SH, CH).
