magnetic amplifier used in lieu of semiconductors
magnetic amplifier used in lieu of semiconductors
(OP)
Since the mag amps are so rugged and handle transients so well, I am considering using them in lieu of semiconductors to rectify sinusoidal ac waveform. My question is, is this possible, and if so, can you point me in the direction to go study how to design it ?
Thank you.

RE: magnetic amplifier used in lieu of semiconductors
for some basic information. I am asking if someone has experience with using mag amps for conversion of ac to dc without using semiconductors in the "power" part of the circuit, the reason being the ability of the amp to handle transients caused by output short circuits, etc ( without using rotating machinery ).
Thank you

It looks from figures 8-215 and 8-216, you could potentially isolate the AC from the diodes, but you're stuck for anything beyond that.
The reason would be that the magnetic amplifier is operating essentially as a linear AC device, while the diodes are non-linear, unidirectional DC devices.

I have seen, in the past, a manual that the US Navy used for their technical people, in which they sent their techs to class to learn about magnetic amplifiers. It was a very informative book, and I wonder if anyone knows how to obtain a copy of it ?
Thanks

Now everyone is wetting themselves over EMP, and trying to make something that can survive. Mag amps look like one possible solution, hence the old technology is gaining some renewed interest.
I wonder how many mag amps you would need to build a microprocessor ? and how fast could it go (chuckle).
RE: magnetic amplifier used in lieu of semiconductors
All humor aside, such mag amps can be designed, though not with the density currently achieved with semiconductors.
