Hallo all together,
I want to make an AC - simulation of a Boost Converter by its Laplace transfer function.
For that I have designed a subcircuit Boost.sub , a symbol Boost.asy and a circuit Control.asc
which you can find in Files->Temp->AC-Analysis problem.
1) When I want to simulate the circuit I get the error "Analysis failed matrix is singular"
Where does it come from and how can I prevent it except the option to switch a resistor between
each node and GND which results in wrong bode plot?
2) Does anybody know a tutorial which shows how to design the boost converter as a subcircuit where I can make doubleclick on it and get displayed the inner circuit?
Thank you very much!!!
Best regards,
Patrick
