摘要:
A high-pressure gas discharge lamp is connected on one side to a lead across the secondary winding of a starter transformer and to a second lead on the second side. Starting energy is applied with a pulse. For this purpose, a controllable switch which becomes conducting on reaching a certain voltage or is connected by a drive is provided in series with the primary winding. A capacitor connected in parallel to the series connection is charged by voltage U between the input terminals across a resistor connected in series and a diode. An input circuit provided between these input terminals of the starter has a capacitor, a protective element or a combination of the two for protection against voltage peaks.
