Power Management References

[Shady Ahmed]

Dear All,
I am studying a course about DC DC converters its types and control loops and battery chargers.. But I am confused and need a good reference and/or tutorials and/or courses. I know about the power management course and book: " R-Fundamentals of Power Electronics by Erickson" ,, but it doesn't cover the control loops for example.

Here are some I have used in the past just purely off the web

Also if you sign up to ridley engineering

https://www.ridleyengineering.com/design-center.html

there is some information regarding control loops in some of the documentation which could be of use.

Hope that helps

there is a book by ray ridley on control which is very good.....part of the name is "volume 1 control"
Basically you are just multipying the error amp transfer fucntion by the power stage and modulator transfer function and then doing this over all frequency range, and read off your gain and phase margins.
The modulator often has "bits" in it which arent explained in the datasheet pf the controller, so sometimes its difficult to actually find out what is the modulator transfer function.
Power stage TFs and error amp TFs are all derived and straightforward...unless youre doing some hybrid convverter
