本研究旨在探討整合式諧振槽之定電壓輸出無線傳能系統應用於小體積需求之場合，由於傳統電磁感應式無線傳能系統之接收端需搭載大量被動元件導致體積過大且設計公式複雜，因此本文針對應用需求設計並分析一套整合型諧振拓樸，透過傳輸側電路設計達成接收端無補償元件之架構。為提升系統穩定性與完整性，研究探討該整合式系統於不同負載條件下之電路動作原理，並同時建構完整之無線傳能小訊號等效模型，此模型提供數位補償器及回授控制重要設計資訊。本研究採用數位補償方法，使系統具備相位餘裕70°與交越頻率1 kHz，確保系統具備良好暫態響應與穩態誤差控制能力。為驗證所提出之整合式架構之效能與可行性，本研究建立一套硬體電路及實驗測試，系統規格依據SAE J2954標準訂定諧振頻率為85 kHz，輸出額定電壓及額定功率目標分別為48 V及500 W。實驗結果顯示，系統於廣泛負載變動範圍下皆可穩定輸出目標電壓，且穩壓誤差低於1%，暫態恢復時間小於71 ms。顯示本文所設計之整合式傳能架構於目標應用情境中具備實用性與高效能，適合整合於生醫植入式設備或無人機等需體積縮減之相關無線供電系統中。

This study proposes a constant voltage (CV) output wireless power transfer (WPT) system featuring an integrated resonant tank, specifically designed for applications with stringent volume constraints. The motivation stems from the limitations of traditional inductive WPT systems, where the receiver side often necessitates a large number of passive components, leading to excessive volume and complex design formulations. To address this, an integrated resonant topology is analyzed and designed to achieve a receiver structure without any compensation components through specialized transmitter-side circuit design. To enhance system stability and integrity, the circuit operation principles under various load conditions are investigated. Concurrently, a comprehensive small-signal equivalent model of the WPT system is established to provide critical design information for the digital compensator and feedback control. By employing a digital compensation method, the system achieves a phase margin of 70° and a crossover frequency of 1 kHz, ensuring robust transient response and precise steady-state error control. To verify the feasibility of the proposed integrated architecture, a hardware prototype was developed and tested. Following the SAE J2954 standard, the resonant frequency is set at 85 kHz, with a target rated output voltage of 48 V and power of 500 W. Experimental results demonstrate that the system maintains a stable target voltage across a wide range of load variations, with a voltage regulation error below 1% and a transient recovery time of less than 71 ms. These findings indicate that the proposed integrated power transfer architecture is practical and high-performing, making it suitable for integration into wireless power systems for biomedical implants or unmanned aerial vehicles (UAVs) where volume reduction is essential.
