本論文旨在研提具有寬輸入電壓範圍之臭氧驅動系統，而此研究乃考量目前臭氧驅動系統使用不同輸入電源作為輸入電壓時，未能有效驅動負載臭氧陶瓷載子芯片，同時諧振電路之電壓增益尚不足以符合負載需求，必須額外加裝變壓器以提升輸出電壓層級。故本論文提出修正型半橋電路，可將輸入電壓轉換為不同輸出電壓準位，同時設計諧振電路使其具有高電壓增益，以節省額外變壓器之裝置成本，進而藉由責任週期之調變控制技術，不僅達成寬輸入電壓範圍需求，實現零電壓切換，並可藉由回授控制，達成輸出定電流之目標。又為驗證本文所提電路之可行性，本文經由模擬軟體與硬體電路進行實驗測試分析，實驗結果輔以佐證本論文所設計之臭氧驅動系統確具實際應用價值。

This thesis proposes an ozone-driven system with wide-input voltage range. This study is motivated because the traditional ozone-driven system often used different voltage sources as the input voltage, leading to the difficulty of driving the ozone ceramic chip. Moreover, since the voltage gain of resonant circuit fails to satisfy the load demands, a transformer to boost the voltage is additionally hence required. To improve these demerits, the thesis proposes a modified half-bridge circuit integrated with a resonant inverter so that input voltage can be converted to different voltage levels. In the study, the resonant circuit is well designed such that it comes with a high voltage gain and the transformer cost can be largely saved. The study also suggests a duty-cycle modulation approach by which the wide-input voltage range is achieved, the zero-voltage switching is realized, and the constant-current is completed with the feedback control. To validate the feasibility of this proposed circuit, both software simulations and hardware experiments have been made. Experimental results support the practical value of the designated ozone-driven system.
