摘要

隨著人們生活水準提高‚各種影音設備也隨之要求愈高‚以前會議、講堂使用之幻燈片、投影片都將被投影機所取代‚但是投影機所使用的燈泡是屬於高密度放電型式的燈泡‚加上各種顯示器也朝著〝碩大就是美〞的方向發展‚不僅亮度對比要高‚色彩影音要求完美‚由於種種均須要電力‚因此‚功率的要求也會愈來愈高。
本文運用兩段式的安定器去配合燈泡去使用在投影機上‚可使用在全球任何規格的電壓‚功率可達到99%以上‚而且切換頻率在66kHz 以上‚相信本篇論文的研究結果‚將對電源的功率的提昇有相當大的助益!

In this thesis, electronic ballast with power factor correction for high intensity discharging (HID) lamp is presented. The proposed topology is a two-stages circuit that requires only one switch and one inductor for each stage. Power factor correction (PFC) stage is boost dc-to-dc converter operating in continuous conduction mode (CCM) to achieve low total harmonic distortion (THD) and proper output characteristics over a wide range of load (10% ~ 90% full load).
This control implementation for against broken lamp can be easily implemented with the proposed circuitry. The high-frequency supply the lamp is given by the flyback converter. Input AC voltages ranges from 90V~260V are allowable for our system with a low DC bus voltage below 450V. It is suitable for electronic ballast with medium power HID lamp. The topologies could work under the circumstance of two 250W fluorescent lamps at 66 KHz switching frequency.
