本文旨在提出應用於非接觸式感應饋電軌道之電動載具三埠式充電∕供電系統架構。主要特點為三埠式系統可將電能轉移作充電及供電，主要動作模式︰(1)非接觸式供電、(2)非接觸式充電。電動載具行駛於非接觸式感應饋電軌道上，電動載具由軌道以非接觸方式拾取電能作為電動載具動力來源，且可將多餘電能利用三埠架構對電動載具上之鉛酸電池充電。為有效提升電動載具充電速度，本文採用Reflex快速充電方式搭配雙向轉換器，並以單晶片作為整體控制核心。單獨測試三埠式系統，其供電模式下效率最高為81.86%。

The purpose of this thesis is to implement vehicle-side tri-port charging/powering system. The main feature of the thesis is that it can save energy to battery or transfer power to output through tri-port system. There are two modes in tri-port system as below: (1) Contactless power supply and (2) Contactless power charge. While electric vehicle is on the contactless power inductive transmission track, electric vehicle can pick up power from track. Besides, battery on vehicle will be charged through tri-port system if secondary picks up too much power. To improve charging rate of the battery, the thesis proposes to use Reflex charging circuit with bidirectional converter and a programmable processor that is the core of the controller. The efficiency is up to 81.86 % in contactless power supply mode and duration of charge is about 35 minute in contactless power charge mode.
