關於此課程：This course teaches how to design a feedback system to control a switching converter. The equivalent circuit models derived in the previous courses are extended to model small-signal ac variations. These models are then solved, to find the important transfer functions of the converter and its regulator system. Finally, the feedback loop is modeled, analyzed, and designed to meet requirements such as output regulation, bandwidth and transient response, and rejection of disturbances. Upon completion of this course, you will be able to design and analyze the feedback systems of switching regulators. This course assumes prior completion of courses Introduction to Power Electronics and Converter Circuits.

A nice course to polish your converter control concepts
It's very good to introduce the method of PID
good course!!!
sa
I have used classical control techniques earlier but could never have thought the way it has been taught here... A whole new approach has been taken up to design the controller for converters in an extremely simple manner... The approximations taken up not only provide a close answer to the actual solution but also change the way a gives a better visualisation for the frequency design...
