| 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。

| Abstract: | 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. |
