A Study on the Power Supply for Endura Electrodeless Lamp

엔두라 무전극 램프용 전원장치 연구

Power supply technique for electrodeless lamps, especially Endura of Osram, is presented in this paper. The power supply uses a conventional power factor correction technique due to its proved performance. But in the inverter stage, resonant converter with parallel loading scheme is used to mitigate the variation of matching circuit characteristics by time varying load. Less performance but sufficient to predict future success compared to Osram's one is verified as a result of experiment of the prototype.
