I have tried PSS + PAC to acquire the bode plot of only the power stage of a buck converter (e.g. dVout/dD where Vout is output of that buck converter and D is the duty cycle of a fixed frequency signal driving the PMOS of that buck converter).
So, the simulated result should follow the well-known and -accepted result of voltage-mode transfer function of a power stage of buck converter, such as with a complex pole located at the resonance frequency of LC of that buck converter. However, the simulated bode plot shows the peak off from the theoretical location.
Anyone has faced similar problem as I did?
Thanks Scottie
