【技术】解析何为整流电路
本文恩智测控向大家解析何为整流电路。希望能为各位工程师带来帮助。
空穴型半导体又称P型半导体,是以带正电的空穴导电为主的半导体。N型半导体称为电子型半导体,即自由电子浓度远大于空穴浓度的杂质半导体。
图 1
PN结二极管
我们将P型半导体与N型半导体结合就能做出二极管和晶体管的半导体元件,叫做PN结。
图 2
二极管具有电流只流向单一方向的性质,叫做整流作用。在二极管P型一侧连接正电极,N型一侧连接负电极,电流就会导通,这样加压的方式叫做正向偏压。
图 3
有正就会有反对不对!是的,我们将P型一侧连接负电极,N型一侧连接正电极,电流就几乎不会导通了,这便是反向加压。
图 4
如果将导电性以表格形式来表示的话是这样的
图 5
电流从正0.6V左右突然开始导通了,是的,如果我们将直流电流反问连接的话,电流就几乎不会导通。
整流电路
利用这种性质,就可以制作出电流只向一个方向流动的整流电路,就是将交流电转变成直流电。
图 6
大多数整流电路由变压器、整流主电路和滤波器等组成整流电路在直流电动机的调速、发电机的励磁调节、电解、电镀等领域都有广泛应用,比较常见的整流电路形式有:
半波整流电路:
电路中使用一只整流二极管构成一组整流电路
图 7
全波整流电路:
电路中使用两只整流二极管构成整流电路
图 8
桥式整流电路:
电路中使用四只整流二极管构成一组整流电路
图 9
倍压整流电路:
电路中至少使用两只整流二极管构成一组整流电路
图 10
整流电路是将交流降压电路输出的电压较低的交流电转换成单问脉动性直流电,这就是交流电的整流过程。整流电路主要由整流二极管组成。经过整流电路之后的电压已经不是交流电压,而是一种含有直流电压和交流电压的混合电压,习惯上称单向脉动性直流电压。

STI3508C本应该是输入3.3V输出12V,但是并没有输出12V,是什么原因?
检查客户板子发现客户的二极管放反了。输入电容无需改为电解电容,增加到10uF/16V的就可以了。
