    Abstract: A method operates a gas-discharge lamp (16) in a transition from a “deactivated” state without an electric arc to a stable “light-generating” state. The method comprises steps of discharging a booster capacitor (C2) in an “acquisition” phase following an ignition-voltage impulse via a current path that conducts a current flowing through the gas-discharge lamp (16) and in which an inductor (L1) having at least one switch (S5) lies in series and cyclically discharging the booster capacitor (C2) by a repeated alternating closing and opening of the switch (S5).

    Abstract translation: 一种方法是在没有电弧的“停电”状态到稳定的“发光”状态的过渡中操作气体放电灯(16)。 该方法包括以下步骤:通过导通流过气体放电灯(16)的电流的电流路径在点火电压脉冲之后的“采集”阶段中放电升压电容器(C2),并且其中电感器(L1) 具有至少一个开关(S5)通过反复交替关闭和断开开关(S5)串联并循环地放电升压电容器(C2)。
