摘要
在电路测试和应用中,经常用到50Hz的小幅值并且幅值可调的三相交流信号源。本文提供了一种这样的信号源电路的设计方法,并且分析了精度影响因素,得出了满足要求的实验结果。
Nowadays in the test of the circuit board and circuit application, there are always need three-phase AC signal which frequency must be 50Hz, which phase should small and can be regulated according to its need. In this paper, a signal source circuit is provided for current demand, and influencing factor of the circuit is analyzed, then a rational result is obtained.
