串联型稳压电源的电路认识串联型稳压电路属直流稳压电源中的一种,其实是在三端稳压器出现之前比较常用的直流供电方法,在三端稳压器出现之前,串联稳压器通常有OP放大器和稳压二极管构成误差检测电路,如下图,该电路中,OP放大器的反向输入端子与输出电压的检测信号相连,正向输入端子与基准电压Vref相连,Vs=Vout*R2/(R1+R2).由于放大信号ΔVs为负值,控制晶体管的基级电压下降,因此输出电压减小在正常情况下,必有Vref=Vs=Vout*R2/(R1+R2),调整R1,R2之比可设定所需要的输出电压值。图中所示只是这也是三端稳压器的基本原理,其实负载大小可以可以把三极管换成达林顿管等等,这种串联型稳压电路做组成的直流稳压电源处理不当,极易产生振荡。现在没有一定模拟功底的工程师,一般现在不用这种方法,而是直接采用集成的三端稳压电路,进行DC/DC转换电路的使用。 01984-2454-0001 Contact Marshalling Panel Rosemount
