hi Tõnn
I tried to simulate a SMPS too many years ago, also at University - modeling it at SPICE.
And I observed that simulation result did not match expected working.
The reason was that PSPICE configuration parameters was not defined properly. ( I discovered It later, after abandon this project ).
Basically, due SMPS simulation requires a wide magnitude float point numbers at numerical analisys, the reduction to default size, increases speed simulation, but affect iteration convergence.
