Tech Talk - How The MEP-002A / 003A Generator AC Voltage Regulator Works

In this tech talk video let's look at the unusual AC voltage regulation system on the military MEP-002A and MEP-003A generator sets and clear up some mysteries about how it functions. I'll explain how the unusual magnetic amplifier works and how it is used in this regulator system.

I am a repairman in the welding equipment field and Lincoln Electric used to use the Mag-Amp output control in many of their designs. Simple but not very efficient. Thanks for explaining this generator control system. I also repair a few AC gensets and I have two of my own (10kw and 15kw) that I must repair before use. So many things to fix - so little time.
Oh, I'm also a growing audio nut and I have couple power amps that I must repair and use. It's a bit tough learning PCB testing and repair in my late 50's, but so worth while.

I know how it goes with too much to fix and so little time! Mag-amps are rugged so it makes sense they would be used in welders. I have seen them in gen set engine control governors and DC power supplies for preregulation. I have some audio equipment repair videos so if you have an interest in that equipment check them out. Thanks for watching!

Does it have Sync and Droop mode?

[@EriksElectronicsWorkbench]

It does not have those features, it was not designed to be paralleled with other generator sets.
