ABSTRACT:
A DC power supply for a gas discharge lamp includes a high voltage starting circuit for supplying high voltage pulses to effect initial energization of a gas discharge lamp, a lower voltage running circuit for supplying a desired average lamp operating current at a substantially constant current to the gas discharge lamp, and a transformer having a primary connected in the high voltage starting circuit and a secondary connected in the lower voltage running circuit. The transformer provides an inductance which acts as a current source inductor to supply current to the gas discharge lamp.
