本文提出一應用於連續導通模式直流/直流轉換器之修正型三端點小信號模型。該模型是一個使用簡易之模型方式，且提供設計者一個較直觀之頻域響應分析方法。
由於傳統之連續導通模式直流/直流轉換器三端點小信號模型之限制，無法將該模型方法直接應用於含有耦合電感之電路。然而本文所提出之修正型三端點小信號模型克服了傳統式的限制，更加擴大了三端點模型之使用場合。不僅可應用於基本轉換器，更可利用本修正型模型直接推導含有耦合電感電路之轉移函數。
本文利用含有耦合電感之連續導通模式高升壓比升降壓轉換器與高升壓比轉換器做為實例，利用本修正型三端點模型推導其轉移函數，最後以實體電路驗證本論文所提模型之準確性。

This thesis proposes a modified PWM switch model for DC-DC converters operating in CCM. It is a simple modeling approach, which provides physical insight for a designer. Due to the limitations of the conventional PWM switch model itself, the conventional model can not be straightforwardly used in converters that contain coupled inductors. However, this modified model overcomes the limitations of the conventional PWM switch model, and expands the application fields of the PWM switch cell. Not only the basic converters, but also the converters with coupled inductor can be analyzed by this modified model.
A high step-up buck-boost converter model and a high step-up boost converter model are revealed in this thesis. By using the modified PWM switch model, the transfer functions can be derived, and the experimental results show good agreements with the theoretical models.
