10.1 Challenges in modeling switch-mode converters

Description

March 27, 2021
In the lecture, we will learn:
  • Switch-mode power converters are not linear time-invariant (LTI) systems.
  • We can’t use transfer functions, pole-zere plots, Nyquist analysis, Bode plots and root locus on non-LTI systems to design controllers.
  • We can make several approximations to yield LTI models that are good enough to control.
