Abstract

In this paper, We have researched about the Electronic Ballast for 250W HPS(High Pressure Sodium) lamp. This Electronic Ballast is capable to operate the Ignition and Steady State Using the Class D LCC resonant tank, and minimizing the full-bridge inverter's Switching Stress by implementation Quasi-square ZC-ZVS Soft Switching Method. And also, We have reduced the heat of MOS-FETs and high frequency switching surge noise using the RCD damp snubber. Therefore, We are sure that the developed ballast has the properties of the stable & reliable Control and the function of minimizing the total noise of the system.

본 논문은 고압 방전램프를 점등시켜 주는 전자식 안정기에 관한 것으로서, Class D LCC 공진 인버터 방식을 이용하여, 램프의 초기 점등, 정상상태를 구동하게 하고, 준구형파로 ZC-ZVS Soft Switching을 구현하여 풀-브리지 스위치의 발열을 최소화할 수 있도록 하였다. 또한, RCD 스너버 회로를 적용하여 스위치 발열 감소뿐만 아니라, 고주파 스위칭으로 인한 서지 전압의 감소를 통한 노이즈를 최소화시켜 제어부의 안정되고, 신뢰성 있는 동작을 가능하게 할 수 있도록 하고, 안정기의 전체적인 스위칭 노이즈 발생을 최소화하였다.
