    Abstract: 本論文主要研製「雙級複金屬燈電子式安定器」,此電子式安定器由昇壓型功率因數修正電路、串聯諧振並聯負載半橋變流器、頻率調變控制電路與微控制器
    PIC12F675 所組成,並使用頻率調變技術之高頻弦波電流驅動複金屬燈管以避免音頻共振現象。燈管功率之控制則偵測直流鏈功率以確保燈管功率在設計範圍之內。
    文中首先介紹複金屬燈之動作原理與特性,說明三級式電子式安定器之電路架構,並描述本文使用之兩級式電子式安定器與頻率調變分析。最後依據所推導電路之
    參數實際製作一可操作於90 至264 Vac 通用輸入電壓之400 W 複金屬燈電子式安定器。實驗結果顯示其具有良好之定功率能力,電路之最高效率為94.8 %,且功率因數值可達到0.99。
    A two-stage electronic ballast for 400 W metal halide lamp with frequency modulation control is presented in this paper. This electronic ballast consists of a boost PFC stage, series resonant parallel loaded half bridge inverter stage, frequency modulation control circuit, and constant power control circuit with digital microcontroller PIC12F675. The boost PFC circuit is operated in continuous conduction mode to achieve high power factor. The series resonant parallel loaded half bridge inverter drives the HID lamp with a high frequency sinusoidal wave current by frequency modulation to avoid acoustic resonance. Finally, a laboratory prototype of 400 W electronic ballast for metal halide lamp with 90~264 Vac universal input voltage is implemented. The measured results show that the HID lamps can be driven with constant power. The power factor is 0.99 and the maximum efficiency of the ballast is 94.8%.
