I am trying to do simulation with Basso's model and find some interesting problem.
Unlike Ridley derived small signal model for ac simulation , Basso uses a uniform model in all dc, ac and transition simulation.
I tried and found some strange error in ac simulation. For example use PWMVM model to do Figure 3-21 simulation. The ac amplitude waveform did not match with book. I re-studied his model and found the formula "EVcp 6 p Value = { (V(dc)/(V(dc)+V(d2)))*V(a,p) }" is root cause. If change it into DCM version "EVcp 6 p Value = { V(dc)*V(a,p) }", the result is right.
So I want to know if anyone meet same problem with me? Or anyone know why is it?
Thank you.
