本論文係研究產業界用於工廠自動化設備供電系統之非接觸式線型感應饋電軌道系統，針對實務應用上所發生的異常現象提出探討和改善方案。由於非接觸式線型感應饋電軌道系統之架構特性，初級側變流器與次級側諧振電路及交流-直流轉換器並無實體連結，當次級側電路出現過載或溫升等異常時，變流器無法立即停止供電，造成取電線圈和諧振電路繼續提供能量，使得異常持續惡化。因此，變流器與次級側電路必須能夠雙向溝通，即時反應各種異常狀況。而在次級側諧振電路與交流-直流轉換器的設計上，則利用電路實測與軟體模擬方式探討其過電壓的異常保護機制，並分別從電壓控制方式和保護元件特性進行分析，檢討電路保護機制的功能性與適用性。另外，本文也提出初級側饋電纜線高頻電流所造成周圍金屬機構的異常感電和電弧破壞現象，經過實驗分析與改善後，已確實能夠有效提升非接觸饋電系統在使用上的安全性。

This thesis is to study the abnormal fault of contactless linear inductive power track system for automated application in the factory. Summarizes the abnormal cases for three types and proposes the solutions. First, the primary side of the contactless power system is separate from the secondary side. In case of the secondary circuit is overvoltage or overheat, the primary inverter could not be shutdown immediately. The pick up coil induces the voltage continuously and worsen the situation. Therefore, the system must have the capability of communication between the primary side and secondary side. Another two types are the mistake designs of the resonance circuit, AC to DC converter in the secondary side to cause overvoltage and the current of the litz wire induces the flashover in the metal rail. The causes of the system abnormalities have been found out through the test and experimental data. The abnormal fault of system can be improved.
