DIY Active Load projects? Or some names to check

[JPortici]

Hi,
I want to start making dc/dc converters and i'm sure a tool i'll eventually need is an electronic load. In my first experiments i've got by with capacitors and power resistors but i'm not sure they are the best tools for measuring load transients.

While the theory and electronic design is somewhat trivial (well, not really true but it's not that hard) and lots of information on the theory side is available.. i still really suck at enclosures,panels and what not.

hence the need for a kit or some used unit (or new! but cheap, in the sub 150 range)

want/need:
-programmable, or some other way to simulate transients (need)
-bnc or test lead output to look at current (want)
-i don't plan going over than 15V rails, 2-4 Amps max so 60W max power at least? (i can also start small and limit myself to 30W

if i made a dual output PS and wanted to test a load transient like insertion of a module that affects both rails... would i need two (sync'd) loads, right?

Re:Load Pro is the only project i was able to find. will look after old stuff to feed my TEA (Test Equipment Addiction)

I've been watching this video series.



It's not that complex, and it is at least programmable.

Oh and trick to making enclosures and panels, get yourself a "case nibbler", makes it easier to make square holes in thin materials.

Check out the Re:Load 2 from Arachnid Labs. They're pretty good, especially the current system! (I have one of their original loads without the case and programmability. I converted it to be programmable by adding a DAC and MCU, then added a huge heatsink which allows me to push it to 50W.)

This guy , https://www.barbouri.com/2017/01/21/linear-mosfet-electronic-dc-load-part-1/ is building one.  I like his choice of 25$ power mosfet


Re-load is nice I have one and for small stuff they are OK, but I wold love one that can also take control input from a signal generator to generate load transitions.

Take a look at this:

He also goes trough whole theory behind it and also stability calculations and such..
