A Digitally Controlled Dual Tracking Power Supply — III

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.

A Digitally Controlled Dual Tracking Power Supply — I

Power supply is one of those things one can never have too many of. I have quite a few already, and my favorite one so far is the Topward 6603A. This dual 60V/3A tracking power supply satisfies most of my needs. I have since added an automatic fan controller, digital voltage readout and a fine voltage adjust knob, making it even more pleasant to use. Another power supply that I regularly use was the one I built earlier last year. That power supply was based on an LM338 5A voltage regulator with added digital voltage/current readouts. But I have always wanted to build a power supply more or less from scratch without using those three terminal regulators. So this time around, I decided to design and build one from the ground up.
