  本論文旨在針對以輕薄短小為特點之小功率電子產品,應用壓電變壓器來研製一交直流轉換器,俾以提供產品所需之低壓直流電源。由於交直流轉換器必須符合電性隔離之安全規範,因此本文將於壓電變壓器的輸入端和輸出端之間加入隔離層,以符合電性隔離之需求,並藉由脈波寬度調變控制調節交直流轉換器之輸出電壓。於交直流轉換器部分,將其規劃成D類半橋諧振電路、輸出整流濾波電路及控制電路三部分來討論。文中最後製作一交直流轉換器並量測實驗結果,其交直流轉換器的工作頻率為117kHz,於輸入交流電壓為100V至120V時,其輸出直流電壓為9V,負載電流為0.3A至1A,最高轉換效率為72%。
 The purpose of this thesis is to present a piezoelectric transformer based AC/DC converter for small power electronic products, which need compact volume. Since AC/DC converters are required to conform to safety regulation. For this reason, the piezoelectric transformer would need to insert an insulation layer between input and output parts to achieve electrical insulation. Furthermore, the output voltage of the AC/DC converter is to be regulated by pulse width modulation control. The proposed AC/DC converter was individually discussed with Class-D half-bridge resonant circuit, rectifying circuit and control circuit. As a result, the AC/DC converter was implemented. Experimental result of the AC/DC converter, the highest efficiency of 72% was obtained at an input voltage of AC 100V~120V, output voltage of 9V, load current of 0.3A~1A, and operating at frequencies of 117 kHz.
