中文摘要 | 本研究目的在探討如何使日光燈的輸入電流諧波成份降低、功率因數提 高、閃爍度降低、電氣效率提高及燈管壽命延長。首先經由升壓式交流變直流的 昇壓型功率因數修正電路以提高功率因數得到直流電壓。再根據燈管電氣特性, 利用半橋串振變頻器將直流電壓以脈波寬度調變技術切割成高頻交流信號,作為 燈管起動以及穩定發光之電路。由實體製作可見,本文所提之電子式安定器在操 作頻率為31KHz時,其功率因數約0.994,峰值因數為1.32,效率為82.1,總諧波 失真為7.1,符合歐美先進國家標準需求,同時並可作為未來發展之基準點。 |
英文摘要 | The goal of this study is to improve the performance oflamp ballast. The performance includes the following indexes:the total harmonic distortion of input current, power factor,light flicker, system efficiency and life of fluorescent lamp.According to the electrical characteristics of fluorescent lamp,a high frequency AC signal is inverted from DC source by ahalf bridge with series resonant inverter used pulse widthmodulation. The DC source is generated by using a boostAC/DC converter in which a power factor correction circuit isadapted. When the operation frequency of ballast is 31KHz, thepower factor, crest factor, efficiency and total harmonicdistortion are respectively 0.994, 1.32, 82.1 and 7.1. Theseexperimental results show that the proposed electronic ballastis able to meet the present goal and porvides a helpful basis forfurther study. |
