Associate editor

I'm Jessica, and as senior editor at EDN, I provide editorial support and help manage the site, overseeing blogs and producing newsletters. When I'm not busy working on EDN, I'm usually enjoying my Boston sports teams, or my favorite bands and TV shows, and working on art projects.

  • @Bruinou2: Constant Resistance and Constant Voltage are both easily implemented in hardware by using a programmable digital potentiometer. Yes, Constant Voltage mode used for solar panel testing, I read somewhere. Consider using one current sensing shunt and a Programmable Gain Amplifier instead of multiple shunts selected by an analog switch or relay.

  • Suggestion from Twitter user @Bruinou2: Why not add constant resistance mode too? Some power supplies cannot regulate output voltage if they are connected to a constant current load.
