本研究旨在建置一套兼具單雙線圈彈性切換機制之感應加熱系統。此研究乃考量現今加熱系統常限制加熱載具之尺寸，致使可選擇之負載尺寸範圍較為有限，並常面臨系統加熱強度過於集中在線圈內局部位置，造成負載受熱不均情形發生，故本論文即致力設計一套具有調控負載受熱能力之加熱系統，使用者可依需求而決定加熱模式，以達成所需加熱效果。本論文分別探討單加熱線圈與雙加熱線圈諧振架構之等效電路模型，詳以進行電路分析與特性比較，並在完成補償元件之計算公式推導後，詳細說明諧振電路之設計步驟，同時制訂回授控制策略，以提高整體系統電路之穩定性。本研究經由硬體實測結果可知，本文所提電路具有操作彈性化與使用便利性之優勢，研究成果可供感應加熱系統開發參考。

The thesis proposes an induction heating system with flexible switching mechanism of single and dual coils. This study is motivated because the induction appliances often encountered the problem of size limitations. Moreover, the heating intensity is often concentrated in a certain area, causing the uneven distribution of temperature. In view of these demerits, the study is devoted to developing a heating system with flexible switching mechanism of single and dual coils so as to own the ability of regulate the heating on the load, and users will be able to decide the heating mode to meet their needs. The paper starts with the investigation of the equivalent circuit model of single heating-coil and dual heating-coil resonant circuits, by which the circuit design procedure will be detailed following the derivation of calculation formula of compensation devices. The feedback control strategy is also made in order to maintain the stability of the proposed circuit can be increased. This study is tested through practical measurements. Test results verify the flexibility and convenience of the proposed method, serving as references for the research and development of induction heating systems.
