The DC voltage on today's transport jets is the output of transfromer rectifiers which are powered by the 115 volt 400 hz generators. There is nothing special about this 28volt DC source. If you have a device that will drop it down to 12 volts you have a realitivly stable 12 volt DC source. This 28 volt DC output is then feed thru circuit breakers to all of the user systems that need it, many in fact most of these systems will step it down and filter it further.
