摘要

本文提出一種結合返馳式與D類新架構之單級高功因電子安定器，此結合返馳式與D類之單級高功因電子安定器，是使用兩組返馳式轉換器與D類諧振換流器來整合成一單級高功因電子安定器，由於有兩組返馳式轉換器，因此對整個電路而言，具有兩組功因修正電路功能，此兩組轉換器是相互交替導通的，使得輸入電流能操作在近臨連續與不連續導通模式之邊界情況，使輸入電流波形更圓滑，達到更低的輸入電流諧波、較低功率開關電流應力等優點。

A new single-stage converter with combined flyback and class D high power factor electronic ballast is presented in this paper. The single-stage converter of combined flyback and class D high power factor electronic ballast is composed of two flyback converters and a class D resonant inverter. The two flyback converters are alternatively turned on to produce an input current near the critical range of the discontinuous conduction mode (DCM) and the continuous conduction mode (CCM). As a result, this proposed single-stage converter with high power factor electronic ballast can provide a smoother input current waveform, lower input current harmonics and less switching current stress.
