本論文擬分析與研製一高壓電源供應器，傳統高壓電源供應器為輸入市電之後，將電壓經由低頻昇壓變壓器升至負載所需之高壓，此升壓方式會因為變壓器的體積過大，造成移動上的不方便。本文利用全橋相移式換流器搭配高頻昇壓變壓器與半波倍壓電路，將電壓提昇至一額定直流高壓，利用高頻切換式電源的技術，可將電路中變壓器的體積縮小，利於未來可攜式電源的發展。文中將針對所提出之電路架構，探討其動作原理並配合理論分析，最後完成一輸出直流電壓60 kV～90 kV，功率滿載為810 W之雛型電路。

In this thesis, a power supply for high voltage generator is analyzed and implemented. The conventional power supply for high voltage generator is utilized the utility line, which should be boosted from a low frequency transformer. However, the low frequency transformers have problems of isolation and large volumes. Thus, the power supply is not portable. To solve the problems, the proposed circuit is composed of a phase-shifted full-bridge inverter, high frequency step-up transformer and a half-wave voltage multiplier. The input voltage is transferred to the high dc voltage for the load. The operating principle and theory of the proposed converter are presented. Finally, a prototype circuit of 60-90 kV/810 W with adjustable output voltage is implemented to verify the theoretical analysis.
