Abstract :
This paper presents a novel solid-state electronic ballast that operates in the megahertz frequency range for use with high-intensity discharge lamps. The ballast is composed of a voltage-source half-bridge inverter with a switching frequency of 1 MHz, a distributed constant line, a parallel LC resonant circuit, an HID lamp, and an igniter circuit. The ballast supplies not only high cold-start voltage to the lamp, but also stable current during lamp operation. The igniter is also capable of supplying the high voltages required to discharge a hot lamp
