5V Power Converters
#1
Hi all,

I'm struggling with getting reliable, clean 5V supply for my system. In my latest OP iteration, I installed my RPI in a case designed to take my 250Gb SSD, and wired in the TOBSUN 10A buck converter that I had previously been using.

I had immediate problems, getting the lighting bolt on the PI screen frequently (low power). I measured output voltage and was only getting 4.5V under load. So, that got changed out to a 5A adjustable buck converter, which I adjusted to just over 5V output. The lightening bolts went away, and everything appeared to be okay.

I thought all was well until I noticed that my ships radio, with a masthead antenna, wasn't hearing VHF as well as my handheld in the cockpit! Clearly, the buck converter was generating so much noise that it was getting into my VHF! This is with 5 or 6 ferrite noise filters clamped over every power and signal wire I could find.

I have one other buck converter to try, but before I do, I'd like to hear what others are doing to get 5V for your systems.
