本文旨在針對新型交流永磁/電磁混合接觸器設計一電子控制模組(ECU)而與一塊永久磁鐵共同結合完成接觸器之接點閉合與分斷工作，尤其使新型交流永磁/電磁混合接觸器獲得前所未有的節能效果。本文所發展的電子控制模組係基於純硬體電路設計而成的，主要訴諸於使新型交流永磁/電磁混合接觸器在指定工作期間之工作成本盡量節省為目的。另外，本文亦就電子控制模組對電磁線圈產生之電磁力及永久磁鐵產生之永磁力如何整合在本文中亦有詳細之理論論述。為實驗之方便，故在實驗室完成本文所提之新型交流永磁/電磁混合接觸器實驗雛型。最後，由實驗雛型的實測數據與電腦數值模型模擬計算結果都明白顯示本文針對新型交流永磁/電磁混合接觸器所提之控制方法對接觸器之驅動控制確實是有效而且是可行的。

This paper deals with the control of a new permanent magnet with electronic control unit (ECU) for reducing the energy dissipation during a complete operation.The methodology developed for the implementation of ECU here is a pure hardware-based approach. It highlights on minimizing the cost of operation over a specified time period rather than a fixed operating point. The practical operating concerns of the proposed ac permanent magnet (PM) contactor and the coordination with the newly designed ECU are also addressed. The developed ac PM contactor has
been implemented as a prototype grade product. Testing results on the experimental prototype and computer simulation model show that the controlling and the energy-saving performances of this newly developed ac PM contactor is effective and feasible.
