Dear all,
Currently, I am reading a switching power supply book by Basso. The file is attached here. On page 102, the author defines the word "DC Transformer" and I got his point. It works as an ideal transformer but only with DC input/output.
On page 105, he performs large-signal simulation. Basically, he just perturbs the duty cycle (d) of a buck converter and observes the perturbation of vout. Then, plot the bode plot: vout(s)/d(s). However, after perturbation, I think the secondary side's current should be the mixture of DC and AC. So, why does he use the DC transformer here?
Thank You
