Optimal Design of the Igniter Transformer for the Automotive HID Lamp Ballast
순시 재점등을 위한 소형 HID램프 이그니터 변압기에 대한 연구
Abstract
In this paper, the requirements for the HID lamp igniter transformer capable of hot strike are described. A small size high voltage (HV) transformer composed of a Rod type ferrite core and aluminum foil is designed. The Electro Magnetic characteristics are simulated with Finite Element Methodology (FEM). The design guideline of the HV transformer that produces an output voltage with a peak value of 25kV and a pulse width of larger than loons for a 35W automotive HID ballast prototype is discussed as an illustrative example.
