Abstract :
In this paper, requirements for the HID lamp igniter transformer capable of hot strike are described. A small size high voltage (HV) transformer composed of a ferrite core and an outer wall is designed. The characteristics such as flux linkage, current density and inductance are simulated with finite element methodology. The design guideline of the HV transformer that produces an output voltage with a peak value of 25 kV and a pulse width of larger than 100 nS for a 35 W automotive HID ballast prototype is discussed as an illustrative example
