最近帮朋友做一个简单的BUCK电路仿真,搭建了电路图,但不知为何老是提示:
> dctr(nslimit no,pins all,siglist /...,stepsize fixed,tend 5,tstep 0.001
*** ERROR "ALG_NO_SOLUTION" *** Cannot find nonlinear system solution.
*** ERROR "ALG_ITERATIONS" *** Too many iterations
Partial results at time=0.0196 were written to the initial point "tr".
execution time= 0.608 sec.
messages given: 2 errors
附上saber设置
试了很多方法,都没有解决,请问这是为什么?
PS:发现去掉那个47e-5的电容C1,就可以仿真,或者将其容值降为70e-6以下也可以,但是这样输出的纹波就会很大了。
