Abstract

Abstract: Xenon flashlamp power supply for solid-state laser has a converter with high voltage conversion ratio. General model is composed of transformer with high voltage conversion ratio and voltage doubler rec-tifier circuit. The purpose of power supply leads dielectric breakdown of Xenon flashlamp and passes current rapidly. When it is passing through the current, it has to limit current to avoid over-heat, damage of electrode and acceleration of gas oxidation which are cause of performance degradation of laser system. In general, the inductor and the resistor are used to limit current. In addition, this type of transformer has high turn ratio to make high voltage. But we can get high voltage using transformer with low turn ratio which is driven by the self resonance. Also, advantage of the self reso-nance is to make simple circuit through the impedance of transformer in resonanct frequency which filters output voltage. I investigated and simplified the main theory for the good characteristics for Xe arc discharge flashlamp.
