제논 램프 구동용 트리거 및 지머 통합 회로

This paper describes the design and implementation of a circuit consisting of a simmer power supply unit and a series trigger unit that can be applicable to xenon lamp driving. An LCC resonant converter based on the continuous conduction mode (CCM) is applied to the simmer circuit and by using the current output control it is possible to maintain the ionization of the lamp which has the negative resistance load characteristic. At the same time, in order to generate a high voltage, a series trigger circuit which has a number of capacitors and diodes is designed. The generated high trigger output voltage could ionize the xenon gas. This paper explains the configuration and features of the integrated circuit system, and verifies the proposed design and stable operation of the xenon lamp. The experimental and simulation results show the not only rationality but also stability of the proposed circuit.
