Paralleling Three Full Wave Rectifier Bridges

You omitted what you though might be an appropriate value for the
simulation.

For John's approximately 100 amp supply, 120 milliohms would be a
reasonable guess. 5% regulation is what I'd want on an industrial supply.
That gives about 344 amps peak diode current.

Like I told your other fake alias: drop dead.

You go first.

Actually less power, for a constant load, since the voltage reduces.

Derive an expression for the voltages and currents in an autotransformer
tapped at, say 30%, hence the flux. Neglect winding resistance.

Since you seem disinclined to do that, I'll ask this:

As you rotate the variac, moving the wiper from 100% downwards, does the
phase of the output change, or stay in phase with the input?

Try it.

That should tell you something.
