The Power Supply System for Xenon Lamp Light Sintering

광소결용 제논 램프 구동을 위한 파워 서플라이 시스템

This paper presents the power supply system which is made of three units: the capacitor charging and main pulse unit, simmer power supply unit, and series trigger unit. The capacitor charging and main pulse unit charges the capacitor bank by using the series parallel resonant converter and the generated main pulses apply to the lamp. The series trigger unit ionize the xenon gas located in the lamp and the simmer power supply unit sustains the ionized condition. It means that the lamp lifetime and efficiency are advanced by reducing the number of triggering. Not only the operation of the proposed system but also the performance of each unit will be verified by the experimental results.
