Resonant Filter Characteristics for Electronic Ballast
안정기의 필터 특성에 대한 연구
Abstract
Electronic ballast uses various resonant type filters, which perform many important functions such as filtering the high frequency harmonics, shaping the proper lamp current waveform and regulating the lamp power. In this paper, characteristics of resonant type filters are reviewed and the matching problem between inverter and resonant filter are described. Transfer function which is always necessary for the circuit parameter design is derived in case of LCC filter type as an example.
