本文探討家用微波爐之開關式高壓直流電源。基於微波爐微波管之高電壓需求，以高匝數比之高頻變壓器升壓，變壓器之一次側為電壓源Class-E電路，二次側為全波倍壓整流電路。為增加控制彈性，以數位信號處理器控制微波爐之輸出功率。本文以IsSpice模擬開關電路之操作及調整共振電路參數，以MATLAB驗證電路方程式，最後實際設計並製作一部110伏特1500瓦之家用微波爐高壓電源以驗證本文之成果。

This thesis studies the design and implementation of a switching power supply for household microwave ovens. Due to the high-voltage requirement of magnetrons, transformers with high turn ratio are utilized. The primary of the transformer is a voltage-source class-E circuit and the secondary is a diode-capacitor voltage doubler. To control the output power of the power supply, a digital signal processor is used. In this thesis, IsSpice is used to simulate the circuit operations and design the resonant parameters. MATLAB is employed to verify the circuit analyses. A 110V 1500W power supply for household microwave oven is finally designed and implemented to demonstrate the thesis.
