Abstract :
A new high-frequency and high-efficiency electronic ballast for high-intensity discharge (HID) lamps is presented. The ballast features an integral resonant ignitor, high efficiency, power regulation, and optional hot strike and fast warm-up capabilities. The ballast can operate virtually any lamp without acoustic arc resonance. The paper presents the topology, operation, analysis, design considerations, and experimental results obtained from a 70 W prototype
