A Study of Distributing Parameters in High Voltage Transformer for HID ballast

This paper studies the effect of distributing parameters in high-voltage transformer. After calculated this parameters by finite element method, the values were validated by experiment result. Good agreement is found. Due to the leakage inductance and stray capacitance, the resonance exhibits certain electro magnetic interference to the circuit. So some methods must be used to reduce the values of distributing parameters in high-voltage transformer. In addition, the high voltage pulse with low current is easy to dissipate in the air.
