本論文旨在研製採用Series-Parallel(S-P)補償架構之無線傳能定電壓輸出系統。本文以一次側之測量數據預測負載端電壓，省去了二次側之微控制器與回傳數據至一次側之無線傳輸，因此系統僅由一次側之微控制器控制，加入模糊增量式比例-積分-微分數位控制(Fuzzy Incremental PID Control)，透過前級全橋轉換器之相移脈波寬度調變(Phase Shifted PWM)調整，使系統輸出在固定負載或變動負載情況下，皆能達到定電壓輸出之目標。本論文首先針對感應線圈電路模型與諧振補償電路特性，進行公式推導與比較，後續說明整體系統軟硬體設計流程，並以電腦軟體模擬分析。為驗證本文提出系統之可行性，本論文將以不同迴授控制方法建置三套無線電能傳輸系統，分別進行各級電路波形實測，並分析系統預測電壓之準確性以及模糊增量式比例-積分-微分控制之穩定性。實驗結果顯示本系統於負載變動情況下，均可維持穩定電壓輸出，且其穩定亦較傳統增量式PID控制優異，因此本論文之研究成果可作為未來無線電能傳輸系統開發參考。

This thesis aims to develop a wireless transfer system (WPT) with constant voltage output using series-parallel (S-P) compensation topology. This paper uses primary side measured variables without the need of secondary side measurement and communication devices between the circuits. In addition, the magnitude of the output voltage has been controlled by using only a single-side controller located in the primary circuit. In this paper, the fuzzy control algorithm is combined with the incremental PID algorithm. Then the phase shift pulse width modulation control of the full-bridge inverter is used to regulate the output voltage, which makes it reach the purpose of constant voltage output when the load is fixed or variable. This paper first conducts formula derivation and comparison of the characteristics of the induction coil circuit model and the resonance compensation circuit. Subsequently, it describes the design process of the software and hardware of the overall system, and simulate with the computer software. To verify the feasibility of the system proposed by this paper, it will build three sets of WPT systems with different feedback control method, conduct actual measurement of circuit waveforms at various levels, and then analyze the accuracy of the load prediction as well as the stability of fuzzy incremental PID control. The experiment results show that the system can maintain approximately constant voltage output under load fluctuations, and the stability is better than the conventional PID control algorithm. Therefore, the research results from this thesis can be utilized as a reference for the development of WPT system.
