本文旨在研發臭氧產生器之電源供應器，電源供應為具有高壓、高頻輸出的單相電流源換流器。本系統整體電源供應器包含交錯式降壓型轉換器、單相電流源換流器及等效電阻-電感-電容並聯諧振負載。交錯式降壓型轉換器作為直流-直流轉換器，輸入側利用三相橋式整流器將市電電壓轉換為直流電壓，再透過控制降壓型轉換器以產生直流電流，達到定功率及定電流源之功能。如此可減少單相電流源換流器之輸入電流漣波量，提高系統容量。單相電流源換流器將直流電流源轉換為交流電源，並接昇壓變壓器，作為臭氧產生器之高壓放電管之電源使用。本文電阻-電感-電容負載的諧振頻率配合單相電流源換流器之輸出頻率，提供負載高功率因數之電源及減少切換損失。
本系統採用32位元之數位信號處理器TMS320F28069作為控制之核心，控制策略皆由軟體程式以C語言完成，有效減少硬體之電路。本系統作臭氧產生器之電源供應端完成輸出功率達1.0kW，此時變壓器一次側輸出電流5.35A，輸出電壓為431V，臭氧濃度百分比為11.15%。本文亦完成由並聯諧振負載模擬臭氧產生器之整合系統，其輸出功率達2.0kW，此時輸出電流有效值為7.84A，輸出電壓有效值為263V，輸出頻率為1kHz，功率因數為0.99，整體系統效率約為91%。由以上之實測結果驗證本文架構與控制策略之可行性。

This thesis aims to develop a high-voltage and high-frequency single-phase current source inverter power supply for ozonizer. The whole system is composed of an interleaved buck converter, a single-phase current source inverter and a RLC parallel resonant load. Interleaved buck converter as DC-DC converter uses a three-phase bridge rectifier to convert grid voltage to dc-link voltage. With controlling the output current of the interleaved buck converter, the features of constant output power and constant output current can be achieved. This control strategy could reduce the value of ripple of the output current and increase the system power capacity. Single-phase current source inverter converts direct current to alternating current, and connects with a transformer as a power supply for ozonizer. This RLC parallel resonant circuit can supply a high power factor and low switching loss output by working at the resonant frequency with the single-phase current source inverter.
The 32-bit digital signal processor, TMS320F28069, is adopted as the system core. All control strategies are accomplished with C language, which can reduce hardware components. The ouput power of the system as power supply for ozonizer reaches to 1.0kW, the ouput current of the primary side of the transformer is 5.35A, the ouput voltage is 431V, and the weight percent of the ozone is 11.15%. The thesis also accomplished a system with a parallel resonant circuit to simulate ozonizer, which output power reaches to 2.0W. The output current is 7.84A, the output voltage is 263V, the output frequency is 1kHz, the output power factor is 0.99, and the system efficiency is 91%. The feasibility of the proposed system structure and control strategy is verified experimentally.
