A transformer-type ignitor for instantaneous restarting of a High Intensity Discharge (HID) lamp was investigated. High-voltage pulses are required to instantaneously restart the HID lamp at high temperature, and obtaining such high-voltage pulses requires a special switch with high voltage and heavy current ratings on the primary side of the pulse transformer. However, conventional semiconductor of switches in general use cannot meet such high ratings. This paper proposes an HID-lamp ignitor using a magnetic switch instead of the semiconductor one, and analyzes its operating characteristics. From analytical results, the optimum design of circuit parameters was derived. A breadboard was implemented to confirm the analysis and design procedure experimentally. Output-voltage pulses of about 10kV were successfully obtained from the input voltage of AC 200V.
