HID LAMP IGNITOR

摘要

An HID lamp ignitor for a lamp including a transformer (92) having a primary winding (94) inductively coupled to a secondary winding (96) operably connected to a lamp output (98); a first switch circuit (100) operably connected between DC voltage (102) and a junction point (104), the first switch circuit (100) being responsive to a first switch signal (112); a second switch circuit (120) operably connected between the junction point (104) and common (124), the second switch circuit (120) being responsive to a second switch signal (132); and an LC tank circuit (140) having the primary winding (94) operably connected in series with a capacitor (142), the LC tank circuit (140) being operably connected between the junction point (104) and the common (124). The first switch signal (112) alternates with the second switch signal (132) to close the first switch circuit (100) and the second switch circuit (120).
