摘要

本文提出一新型獨立預熱電路搭配半橋式電流源並聯諧振電路之模組化電子安定器設計，此獨立預熱電路內藏之預熱變壓器在0.5秒的燈絲加熱完成後，立即停止工作，其中，預熱變壓器之預熱線圈直接並聯在燈絲兩端，減少了燈管在穩態條件下的燈絲損耗。本研究以4燈32瓦T8的直管螢光燈負載條件，實驗評比三種起動方式：非預熱起動型、預熱起動型和高效能預熱起動型電子安定器之安定器流明效率。最後，證明高效能預熱起動型電子安定器符合2014年美國能源局的安定器流明效率要求，可以直接取代傳統的預熱起動型電子安定器，減少照明用能源的消耗。

The paper presents a novel high efficiency half-bridge current-source parallel-resonant electronic ballasts modular design with an independent preheating circuit. The independent preheating circuit stops after 0.5 seconds of filament preheating. The windings of the preheat transformer couple with filaments of the lamps to reduce power loss. Based on the use of four F32T8 linear fluorescent lamps, the experimental results show Ballast Luminous Efficiency (BLE) performance with three kinds of starting signature: Instant-start, rapid-start and programmed-start. The programmed-start electronic ballasts comply with 2014 DOE Ballast Luminous Efficiency to save energy for lighting and are able to replace the traditional rapid-start electronic ballasts directly.
