开关电源结构与原理时间：2013-01-05 来源：作者：PC电源知多少个人PC所采用的电源都是基于一种名为“开关模式”的技术，所以我们经常会将个人PC电源称之为——开关电源(Switching Mode Power Supplies，简称SMPS)，它还有一个绰号——DC-DC转化器。
本次文章我们将会为您解读开关电源的工作模式和原理、开关电源内部的元器件的介绍以及这些元器件的功能。
●线性电源知多少目前主要包括两种电源类型：线性电源(linear)和开关电源(switching)。
线性电源的工作原理是首先将127V或者220V市电通过变压器转为低压电，比如说12V，而且经过转换后的低压依然是AC交流电;然后再通过一系列的二极管进行矫正和整流，并将低压AC交流电转化为脉动电压(配图1和2中的“3”);下一步需要对脉动电压进行滤波，通过电容完成，然后将经过滤波后的低压交流电转换成DC直流电(配图1和2中的“4”);此时得到的低压直流电依然不够纯净，会有一定的波动(这种电压波动就是我们常说的纹波)，所以还需要稳压二极管或者电压整流电路进行矫正。
最后，我们就可以得到纯净的低压DC直流电输出了(配图1和2中的“5”)配图1：标准的线性电源设计图配图2：线性电源的波形尽管说线性电源非常适合为低功耗设备供电，比如说无绳电话、PlayStation/ Wii/Xbox等游戏主机等等，但是对于高功耗设备而言，线性电源将会力不从心。
对于线性电源而言，其内部电容以及变压器的大小和AC市电的频率成反比：也即说如果输入市电的频率越低时，线性电源就需要越大的电容和变压器，反之亦然。
由于当前一直采用的是60Hz(有些国家是50Hz)频率的AC市电，这是一个相对较低的频率，所以其变压器以及电容的个头往往都相对比较大。
此外，AC市电的浪涌越大，线性电源的变压器的个头就越大。
由此可见，对于个人PC领域而言，制造一台线性电源将会是一件疯狂的举动，因为它的体积将会非常大、重量也会非常的重。

产生高输出电流时输出低电压的降压DC/DC转换器模块介绍为了满足系统设计人员的这些和其他严格要求，德州仪器（TI），凌力尔特公司（Linear Technology）和Intersil等供应商已经准备好使用最少数量外部的集成降压DC/DC转换器模块无源器件。
德州仪器（TI）已经发布了许多适合这些需求的简单切换器。
其中一个解决方案是LMZ31520，一个20 A DC/DC转换器，可提供0.6 V至3.6 V的可调输出电压，效率高达96％。
高功率Simple Switcher采用薄型QFN封装（图1）中的功率MOSFET，屏蔽电感和无源元件，仅使用三个外部元件即可提供具有低输出电压的完整降压DC/DC模块。
图1：TI集成简易开关LMZ31520的功能框图。
使用V ADJ和AGND引脚之间的外部电阻RSET，可以很容易地将LMZ31520的输出电压从0.6 V调节到3.6 V.产品数据手册中的表格分别为输入PVIN为12 V，5 V和3.3 V的欧姆提供了计算的RSET值。
推荐的开关频率为500 kHz，可通过保持FREQ_SEL引脚开路来配置。
事实上，同一产品数据表中的另一个表提供了各种RFREQ电阻值的开关频率值，当它连接在FREQ_SL引脚与PGND或V5V引脚之间时。
从3.3 V电源供电由于目前几种应用必须使用3.3 V电源轨，因此较低输入电压的DC/DC转换器正变得越来越流行。
虽然这种电源可以有效地切换较低的输入电压，但它们仍然需要更高的偏置电压来驱动一些内部电路。
因此，从3.3 V轨道容易产生更高偏置电压的能力变得越来越重要。
为了简化这项任务，TI提供TPS60151，一个输入范围为2.7 V至5.5 V的电荷泵。
因此，它可以将3.3 V输入升压至5.0 V输出，电流高达150 mA。
由于空间非常重要，它采用紧凑的2 x 2 mm QFN封装。
因此，当从3.3 V总线为LMZ31520供电时，TPS60151可用于为转换器模块产生偏置电压如图2所示。
