稳压电源的分类方法繁多,按输出电源的类型分有直流稳压电源和交流稳压电源;按稳压电路与负载直流稳压电源的连接方式分有串联稳压电源和并联稳压电源;按调整管的工作状态分有线性稳压电源和开关稳压电源;按电路类型分有简单稳压电源和反馈型稳压电源,等等。如此繁多的分类方式往往让初学者摸不着头脑,不知道从哪里入手。其实应该说这些看似繁多的分类方法之间有着的层次关系,只要理清了这个层次自然可以分清楚电源的种类了。
既然我们谈的是稳压电源的分类,那么首先就应该清楚电源的输出是什么,是输出直流电还是输出交流电。这样个层次就出来了,首先应该根据电源的输出类型来分类。接下来的分类就要麻烦一些,可以按稳压电路与负载的连接方式分类,也可以按调整管的工作状态分类。其实了解一下我们身边的电子设备会发现实际应用中稳压电源有两个区别很大的种类,一种是比较简单的电子设备中广泛使用的线性稳压电源,比如收音机、小型音响等;一种是复杂电子设备中广泛使用的开关稳压电源,比如大屏幕彩电、微型计算机等。这样看来第二个层次的分类我们可以根据调整管的工作状态来分类。接下来的第三个层次的分类就是根据稳压电路与负载的连接方式来分类。再往下面细分由于不同的电路特性相差太大,就不好一概而论,应该根据每一个具体类别的特性进行分类区分了。
直流稳压电源可以分类两类,包括线性和开关型。
线性稳定电源有一个共同的特点就是它的功率器件调整管工作在线性区,靠调整管之间的电压降来稳定输出。由于调整管静态损耗大,需要安装一个很大的散热器给它散热。而且由于变压器工作在工频(50Hz)上,所以重量较大。
该类电源优点是稳定性高,纹波小,可靠性高,易做成多路,输出连续可调的成品。缺点是体积大、较笨重、效率相对较低。这类稳定电源又有很多种,从输出性质可分为稳压电源和稳流电源及集稳压、稳流于一身的稳压稳流(双稳)电源。从输出值来看可分定点输出电源、波段开关调整式和电位器连续可调式几种。从输出指示上可分指针指示型和数字显示式型等等。
开关型
与线性稳压电源不同的一类稳电源就是开关型直流稳压电源,它的电路型式主要有单端反激式,单端正激式、半桥式、推挽式和全桥式。它和线性电源的根本区别在于它变压器不工作在工频而是工作在几十千赫兹到几兆赫兹。功能管不是工作在饱和及截止区即开关状态;开关电源因此而得名。
开关电源的优点是体积小,重量轻,稳定可靠;缺点相对于线性电源来说纹波较大(一般≤1%VO(P-P),好的可做到十几mV(P-P)或更小)。它的功率可自几瓦-几千瓦均有产品。价位为3元-十几万元/瓦,下面就一般习惯分类介绍几种开关电源:
