摘要
在半波整流电容滤波电路中,由于负载电阻上输出电压的脉动较小,接近于直流电。给负载电阻的测量带来了很大误差,本文介绍了一种方法,可以准确测量电阻的大小,不受脉动大小的影响。可作为一个较好的设计性实验课题。
In the half-wave rectifier capacitance filter circuits, the low output pulsating voltage from load resistor will lead to large error in the measurement processes of load resistance. A new method was presented to accurately measure the resistance of the circuit irrespective of low output voltage. It is believed that the proposed method can be used as a projection-oriented experiment.
