ABSTRACT:
A starting circuit for discharge lamps includes a current limit device, a full wave rectifier circuit and a Cockcraft-Walton's circuit which are connected between a d.c. discharge lamp having a cathode and an anode and the input terminals of an a.c. power source. Moreover, the Cockcraft-Walton's circuit is constructed by sharing a rectifier with the full wave rectifier circuit and a preheating circuit is provided for the cathode and includes another rectifier of the full wave rectifier circuit and a switching device.
