摘要

本研究為發展電源同步降壓轉換器技術，開關轉換器技術大概分為六類，分別為電路拓樸與控制、功率半導體與IC器件、電感變壓器與電容等。儲能元件，而這次研究的內容比較於偏向非隔離式直流轉換器，包括六個基本轉換器(Buck, Boost, Buck-Boost, Cuk, Sepic, Zeta)。而本篇技術報告主要是由功率半導體以及IC設計的角度出發，電源開關轉換器的原理就是靠著半導體開關元件的導通與關斷，達到將輸入端直流電壓脈衝形式，作為後續能量轉換與處理的基礎，不同的元件就有不同的特性，包括直流穩態，交流動態，溫度特性等。

This research is to develop the power supply synchronous buck converter technology, switching converter technology is roughly divided into six categories. They are circuit topology and control, power semiconductors and IC devices, inductors, transformers, and capacitors. Energy storage components and this study compare favorably to non-isolated DC converters, including six basic converters (Buck, Boost, Buck-Boost, Cuk, Sepic, Zeta). This technical report is mainly from the perspective of power semiconductors and IC design. The principle of the power switching converter is to rely on the turn-on and turn-off of semiconductor switching elements to achieve the DC voltage pulse form at the input end as a follow-up energy conversion and processing. The basis is that different components have different characteristics (including dc steady state, ac dynamics, temperature characteristics, etc).
