ZVT-PWM 부스트 컨버터를 이용한 무전극 램프 구동 시스템

Electrodeless Fluorescent Lamp System using A New ZVT-PWM boost Converter

In this paper, an application of the ZVT-PWM(zero-voltage-transition) boost converter, which has great advantage on miniaturization and high power density, to the power factor correction circuit of the EFL(electrodeless fluorescent lamp) inverter is studied. The operation principles of the converter are described to identify the power factor correction characteristic of the inverter. Experimentally obtaining the high power factor above 0.99, it is verified that the power factor correction of the EFL inverter successfully achieved.
