弱耦合感應電力傳輸系統(Loosely Coupled Inductive Power Transfer System, LCIPTS)，主要是經由磁場耦合將電能自一電源傳輸自另一可動之負載，而無需直接透過電力線連接，故具有避免產生火花或觸電危險的優點。然而由於國內有關非接觸型電力傳輸技術之研發與應用仍相當有限，有鑑於其未來許多特殊場合之應用潛力又相當廣泛，因此本論文主要之研究目的是針對弱耦合感應電力傳輸系統之優點，將之應用於切換式直流電源供應器上，作一完整且深入的探討。

本論文主要貢獻有四，第一，就本論文所探討的架構來說，弱耦合感應電力傳輸系統共有三個可工作於最小輸入伏安容量的頻率，即WL、Wo及WH。第二，利用串聯與並聯共振頻率相等情況下將 及 等甚為複雜的公式，導演出一較為簡單的公式，以方便分析與設計用。第三，利用吾人所提在交流輸出情況下不同操作模式的電路特性，可以將控制電路都作在弱耦合變壓器的一次側，更確切符合其一、二次側鐵心繞組可分離式的特性。第四，吾人將此複雜的技術歸納出一套簡易的設計準則，可以根據此準則很方便地設計非接觸型切換式直流電源供應器的電路參數。最後並實際製作一雛型電路以驗證所提非接觸型切換式直流電源供應器之可行性。

Loosely coupled inductive power transfer system is designed to deliver power efficiently from a stationary primary source to one movable secondary load over relatively large air gap via magnetic coupling without wires and connectors. It has advantages of avoiding the dangers of sparking and the risk of electrical shocks. However, the research and development about this technology is quite limited at present in this country. Considering its potential development and applications in the future, it is vary worthy to study and explore the fundamental principle and design guideline of a noncontact switching mode DC power supply.

The contributions of this thesis may be summarized as follows. First, three resonant frequencies, namely , and are obtained which can achieve minimum input volt-ampere capacity of the loosely coupled inductive power transfer system as well as maximum output power. Second, in order to analyze and design this system more efficiently, by assuming that the series resonant frequency is equal to the parallel resonant frequency, simple analytic formulas of and are obtained. Third, according to characteristics of different operation modes in AC output situation, output voltage or current can be controlled from the primary side of the transformer. Fourth, a simple design procedure and some analytic formulas are proposed to simplify the design process. Finally, a prototype is also constructed to verify the feasibility of the proposed theory.
