本論文的目的是針對目前可攜式電子產品對高效率，低成本的電源技術之持續增加的需求而探討直流電源轉換技術。傳統的遲滯控制轉換器有簡單、低成本的優點，但其交換頻率會随輸入及輸出條件而改變是它的缺點。本文探討直流轉換器遲滯控制電路對暫態響應及交換頻率穩定性等特性之影響。利用電路分析、模擬與實作來驗證比較遲滯控制電路特性，以得到一電路簡單且具良好的暫態響應之遲滯控制轉換器。

The purpose of this thesis studies a DC to DC converter technology that meets the increasing demand of a high efficiency and low build cost converter architecture for the portable electronics devices. Traditional hysteretic control converter is easy to implement with low build cost, but the disadvantages come with it is the varying switching frequency with the input and output condition changes. This thesis investigates the characteristics of hysteretic control circuits for the DC to DC converters, including transient response, switching frequency stability, and so forth. By using analysis, simulation, implementation, and comparison, a DC to DC converter with a simple hysteretic control circuit and a good transient response can be obtained.
