In the deep recesses of my mind I seem to remember
something about S/360
machines using a motor generator.
If I am right was this to create a stable power source at a certain
frequency or voltage?
Those systems predate my experience by roughly 25-30 years.?
But once
you go through the trouble of adding such a thing as a motor-generator,
then you can make the generator a poly-phase device (say, 12-phase) and
get a much lower ripple in a full-wave polyphase rectifier; you can also
easily control the output voltage by acting on the generator's rotor
field current.? This sort of equipment is used for industrial processes
requiring DC at thousands of amps; the polyphase setup makes it possible
to leave out the output filter capacitors.
