非接觸式電源傳輸系統常應用在特殊需求之場合，由於弱耦合變壓器磁性元件結構較為複雜，並產生相當大之洩漏電感，導致常用的穩壓控制方法與策略需以較多元件與複雜控制策略才得以完成。本文利用受控式整流機制，將全橋受控式整流器設置於弱耦合變壓器二次側，兼具穩壓與整流功能，藉以降低系統二極體與功率半導體元件使用數量。在一次側則以電壓饋入式換流器作為電壓源，並採用平板型弱耦合變壓器與二次側全橋受控式整流器搭配串串補償網路，研製低成本非接觸式電源穩壓器。為實際驗證所提出穩壓器之功能，本文將其應用於電池定電流/定電壓充電場合，以驗證穩壓控制器與系統的可行性。
依實驗結果顯示，輸入直流電壓為60 V，輸出電壓為43.5 V，氣隙為7 mm時，當最大輸入功率為282 W時、輸出功率為250 W，此時，系統整體效率約為89 %；而當氣隙為16 mm時，輸入功率為474 W、輸出功率為391 W，效率略降為83 %。

Contactless Power Transmission Systems (CPTS) are often used in many special fields. Due to the magnetic structure of the Loosely Coupled Transformer (LCT) bring out the large leakage inductance, more components and complex strategies are required in existing regulation methods or/and strategies. The Controlled-Rectifier (CR) circuit is applied in this thesis for regulation and rectification in the secondary side of the LCT, with CR and its controller to reduce the required component number. A voltage-fed inverter in primary, planar LCT, and CR circuit are designed for verifying the theory and control strategy for a low cost contactless regulator. To prove the feasibility of regulator and system, the regulator is used in the CC/CV battery charge.
The experiment result shows 89 % overall system efficiency while the input voltage is 60 V, output voltage is 43.5V, air gap is 7 mm and the input/output power is 282 W/ 250 W. Also, overall system efficiency is 83 % while the air gap is 16 mm, the input/output power is 474 W/391 W.
