本文主要為完成一部高頻高壓電暈產生器。電源採用串聯式負載共振轉換器供應，並應用高頻高壓電暈放電器產生電暈。本研究利用串聯負載共振轉換器組成之電源驅動器，以MOSFET為高頻高壓功率切換元件，利用高頻升壓變壓器達到高頻高壓輸出電源，使高壓放電極達產生電暈放電。
高頻高壓變壓器負載與暈放電極皆為諧振電源迴路的一部份，高頻高壓變壓器含有可觀的雜散電容，本文以外加電感量測法，建構一包含雜散電容之變壓器等效電路。本研究利用電路特性量測分析，建構電暈放電極等效電路，整合電暈放電器之高壓放電等效電路，並利用IsSpice軟體電路模擬分析，驗證本論文等效電路建立之準確性。本論文得出等效模型後並配合諧振電路之分析，建立高頻高壓電暈電源共振參數匹配之設計準則。最後完成一部交流輸入電壓220V/60Hz之1kVA和輸出峯值為8kV/22kHz的串聯式負載共振轉換器，以驅動高壓電暈放電器。

This research utilize the power supply composed of a series load-resonant converters, MOSFET as the high-frequency high-voltage switch, and made use of the high-frequency step-up transformer to output high-frequency high-voltage power, so that the high-voltage discharge electrode could generate coronas.
The high-frequency high-voltage transformer and corona discharge electrode all belong to the resonant power circuit. The high-frequency high-voltage transformer contains considerable stray capacitance. This study utilized the inductance measurement method to construct the equivalent circuit of transformers which contained stray capacitance, applied the circuit measurement analysis to construct the equivalent circuit of corona discharge electrode, integrated the equivalent circuit of high-voltage discharge of corona dischargers, as well as to employ the IsSpice software for circuit simulation in order to verify the accuracy of equivalent circuits constructed in this research.
