The heart of the device that [Kerry] designed is based on 6 power MOSFETs, a few operational amplifiers and an Arduino compatible ATmega328p microcontroller. Sense resistors are used to measure how ...

First, the easy choice: How to power the buck-boost converters. They need at least 18V in order to supply full current output at 32 V. Note that I can’t use a common supply for the modules, as input & ...

The design challenges for a high-power electronic load extend beyond the electronics. The best electronic load circuit will not function well without a good connection to the device under test. The ...

This third and final part of the series discusses mechanical and thermal design, including connectors, heatsinks and cooling, and overpower protection. The design challenges for a high-power ...
