| 摘 要： | DC-DC转换器因其相比于传统的线性稳压器具有较高的电源转换效率,而被广泛地应用到各种现代电子设备中。同时随着电源整流技术的不断进步,DC-DC转换器也正在从以肖特基二极管作为续流二极管的异步整流模式向同步整流模式转变。同步整流式DC-DC转换器具有极高的电源转换效率(可超过95%),是各种手持设备电源设计的首选。本文从分析同步降压式DC-DC转换器的闭环增益和相位曲线入手,研究了多种条件下如何实现同步降压式DC-DC转换器的稳定性设计。

| Abstract: | Due to the high efficient, DC-DC converter is widely used in modern electronic devices. As the technology of power rectifier goes on,DC-DC converter is transferring from asynchronous mode to synchronous mode. The efficient of synchronous DC-DC converter can be more than 95% ,which is the first choice of cellular devices. This paper will focus on the analysis of stability of synchronous buck DC-DC converter. |
