#1楼主：multisim 10仿真问题
文章发表于：2008-09-22 02:34
做了个PWM转4-20ma的电路。原理：函数发生器产生一个500hz, vpp:1.65v,偏移
:1.65v的方波，经光电隔离，二阶滤波转为直流电压。再经V/I转为电流，二个万
用表测量电流。老是出现下面以下仿真错误：
A simulation error has occurred. Would you like to run the Convergence Assistant to attempt to resolve this problem automatically?
电路见附件，各位帮忙看看，问题出在哪里？？
