Ignition device i.e. superimposed-type ignition device, for igniting alternating current high-pressure gas discharge lamp in motor vehicle, has inductor with high impedance for high-frequency voltage arranged in series to voltage terminal

摘要

The device has a capacitor (C2) with a low impedance for a high-frequency voltage and a high impedance for a low-frequency operating voltage arranged between operating voltage terminals (X1, X2). Inductors (L1, L2) e.g. chip ferrite beads, with a high impedance for the high-frequency voltage and a low impedance for the low-frequency operating voltage are arranged in series to the operating voltage terminals. An inductor (L3) with a high impedance for the high-frequency voltage is arranged in series to an auxiliary ignition voltage terminal (UZH).
