Help for Micro CaP

[paffii]

Hello,
this post can be closed. I did mistakes in shorting some wires in components, error found 🙂


Hello,
is there someone working with Micro Cap? I am beginner with spice and i want to simulate a schematic that is from a book and it works in real very nice.
It is a booster from 12 to 200V with 555 and FET. In Simulation i only get 23V on the output, but it should be over 180V.
Maybe i have an error in there, but i cant find. It would be nice if someone is using Micro Cab and would load the circuit to check.
Thanks,

Andreas

For those without Micro Cap how about a schematic in case we can spot the issue?

oh, you are riht, i forgot..

D1 looks to be in the wrong place? And C3 is shorted out by the MOSFET which can't be right.

oh no, that is really a fault i made, sorry. I have to change it at once..thank you for opening my eyes..

i removed the error, but it still isnt working, no output voltage..
