ABSTRACT:
The invention relates to an electronic ballast, to an illumination device including the electronic ballast and an associated high-pressure discharge lamp, and to a corresponding operating method for a high-pressure discharge lamp, in which resonance excitation is used to generate a voltage-increased power for a transfer phase of the lamp Lp after starting.
