本論文旨在研製ㄧ串聯諧振式高壓電源產生器，其主要應用於高功率電氣設備測試方面。在高壓測試程序中，高壓待測設備之端點阻抗特性近似一電容性負載。因此，應用串聯諧振方法於本系統中，而其待測設備即視為諧振電路中之電容器。本論文所提之系統為一標準二階系統，故可藉由系統的暫態響應來估測出系統諧振頻率。此外，利用最小化待測設備之端電壓總諧波失真度，進而監控系統諧振情況。由於系統諧振頻率是由元件所決定，故需ㄧ可調數位帶通濾波器以解析出待測元件之端電壓基本波成份。本論文採用擾動觀察法來追蹤系統諧振頻率，且應用數位信號處理器調整輸出電壓準位。最後，經由模擬和實驗的結果驗證本論文所提之方法確具可行性。

The purpose of this thesis is to implement a series resonant type high voltage generator used for testing high power electric device. Under high voltage testing procedure, the impedance characteristic of the terminal of the under-test device is similar to capacitance. Therefore, the series resonant method can be employed with treating the device terminals as the capacitor needed in the resonant circuit. The proposed system is a standard second-order system, so the resonant frequency can be estimated through the transient responses of the system. Besides, the resonant condition is monitored by minimizing the total harmonic distortion(THD) of the voltage applied to the device terminals. Because the resonant frequency is device dependent, a tunable digital band-pass filter is designed for separating the fundamental component from the output voltage. In this thesis, we use perturbation and observeation method to track the resonant frequency of the system. A DSP-based controller is employed to regulate the output voltage. Both the simulation and experimental results are obtained to show the validity of the proposed system.
