In this post I'm going to look at the effect of inductance in the output circuit that the load is controlling. Although you may not be specifically driving an inductor, the leads that you use have some inductance and this will have some effe...
In this post, I want to look at the circuit as a servo loop. At this point I probably need to throw in a bit of theory (which I don't understand all that well). This is going to be fast and furious and won't cover the ground in the way that an e...
I was previously doing these posts as part of Jan Cumps' WIP Programmable Electronic Load blog, but that's now so extensive it's getting quite cumbersome to work with and, since this is all of fairly general interest, I thought I'd carry on wit...
