ABSTRACT:
A discharge lamp starting device such as for a fluorescent lamp in which a nonlinear capacitor is connected in parallel with a discharge lamp with a Zener diode connected in series with the nonlinear capacitor. A semiconductor switching device, such as a diode thyristor, is connected in parallel with the discharge lamp. Due to the presence of the Zener diode, the semiconductor switching device can have a wide range of threshold voltage so that the cost of the device is low.
