[Milsurplus] [ARC5] Quieting A DC/DC Converter

[Bob kb8tq]

Hi

The gotcha with fuses as protection for something like this is that the fuse is likely
to be protected by the inverter dying. Coming up with proper (high speed) protection
is something that can be done. It just adds cost ….

Since this is a square wave, the transformer and how it interacts is *not* a simple thing.
Load removal may be an “interesting” event right along with shorts. Often things get 
tuned with R/C networks to calm it all down. Again, not life or death. Just more parts 
and a bit more time playing with the design.
