The invention relates to a DC power supply utilizing DC to AC to DC conversion with pulse to pulse current mode IC controlled PWM modulation at an above-sonic repetition rate (e.g., 30 Khz) in a degenerative feedback loop to achieve output regulation.

The powder supply, which includes a step-down transformer and a choke input LC filter, is designed for energizing a short-arc, lamp and provides glow to arc transition energization, regulated run energization, and igniter controls. Output regulation may be either of current or power and is based on using a current emulating the current flowing into the filter choke or using both the emulating current and a voltage sensed in a separate secondary winding of the transformer. A novel ramp generating circuit which preserves loop sensitivity at high power loads and a novel method of powering the controlling IC are also disclosed.
