    Abstract: 本文分析設計一高壓鈉氣燈電子安定器，此電路架構包含電磁干擾濾波器、倍壓整流濾波器、D類串聯諧振並聯負載換流器、高壓點火及迴授電路。電磁干擾濾波器可將功率晶體於高頻切換時，所產生之高頻諧波電流濾除；倍壓整流濾波器採最簡單之半波倍壓整流濾波電路，將市電升壓整流成直流電以供使用；D類串聯諧振並聯負載換流器乃提供鈉氣燈穩態後燈管所須之功率，另以TL-494脈波寬度調變控制器（PWM）為其驅動電路，可使電路具調光功能。高壓點火電路在產生一高壓脈衝，來激發鈉氣燈填充氣體崩潰、導通；迴授電路則在鈉氣燈崩潰導通後立即將高壓點火電路消除。本文實作一150W高壓鈉氣燈電子安定器，以驗證電路設計之理論。
    In this thesis we design and implement a high pressure voltage electronic ballast for a sodium lamp. In the circuit structure it consists of an electromagnetic interference filter, a voltage- doubler rectificable filter, class-D serial-resonant and parallel- load inverter, a high voltage ignition circuit and a feedback circuit. The electromagnetic interference filter will filter out the generated high frequency harmonic current when the power crystal device makes switching at high frequency. The voltage- doubler rectificable filter is a simple half- wave voltage doubling rectificable circuit to rectify the household voltage into applicable direct voltage. The class -D serial-resonant and parallel- load inverter provides the necessary power for the tube after the sodium lamp reaches its steady state. The driving circuit uses IC-TL-494 as the Pulse Width Modulation (PWM) controller which enables the circuit possessing the capability to modulate light. The high voltage ignition circuit generates a high voltage pulse to avalanche and conduct the gas filled in the sodium lamp . The feedback circuit is to eliminate the high voltage ignition circuit right after the sodium lamp is avalanched and conducted. We practically implement an electronic ballast for a 150 W sodium lamp to verify and validate our designed circuit.
