Outpout Impedance Plot

Hello Everyone,

I have a question that someone may know better than me while doing the Bode plot for output impedance.  It seems that in Simulink you will get a plot of iLoad/vout if you plot it normally.  Do we plot 1/smm or smm (in the coding terms of BodePlotter_script.m) while using iLoad and Vout as the variables?

I would expect the output impedance to be in a "v" form like on Figure 8.65 in the text, but it looks inverted to me when I plot smm... any insights?

    Olga,
    I think ssm does not need to be changed in the script. The important thing is where the input and output points for linear analysis are defined in the simulink model. Also, the impedance plots you mentioned don't include RL, Ron, Resr like our model does. I think the plot should be different as a result.

    Thanks for the input, I think you are correct
