    摘要: A lamp start, hot-restart and operating circuit for a high wattage, high intensity discharge lamp (30) includes cascaded resonant circuits with capacitors (12,18,24) and series-connected inductors (14,16) con­nected to an AC source. A pulse circuit (34) including two pulse tansformers (28,29) supplies streamer-forming current, the secondary windings of the pulse transformers (28,29) being connected in series with the lamp (30). When the lamp (30) commences normal operation, the operating current energizes a relay (40) to remove the capacitors (18,24) and pulse circuit (34) from the operating circuit, allowing the inductor to function as the lamp ballast.
