Hey, for all you folks talking about small transformers and signal diodes
to do the job, note the OP said he needed 75 watts. With normal
conversion efficiencies, this is about 4 or 5 AMPS from a 24 volt supply.
We ain't in small signal land any more, Toto.

What makes you think you need that much wattage to spin up a small gyro
motor?

You are correct that the circuit I described will not supply more than a
watt or so, but it was enough for my application, which was what I was
describing. The original poster said he was an EE, so I did not feel the
need to elaborate.

If one were to add 3 driver transistors after the diodes (using the 24v
Vcc), and be sure to use at least 2 amp (low side) transformers, even this
75 watt load could be supplied.
