In part 1 of this series of blog postings, I showed my preliminary design of a dual tracking linear power supply. In part 2, I showed the completed design and also the finished power supply circuits. And as promised last time, I have made a couple of videos showing the measurements of a few key parameters and will share the results here.

    Very interesting and educational.

    I’m designing my own digitally controlled switch-mode power supply and I’m sure I will apply some of what I’ve learned from Kerry’s posts.
