[ARC5] Vibrator Power Supplies

[Robert Eleazer]

I've had one experience with vibrator power supply transformers on 60 HZ AC.  At the TRW swap meet in the early 80's I picked up a UHF RCA Carfone for $1.00.  It had a couple of large power transformers designed to allow operation on either 6V or 12VDC 

I used the transformers  to make a 12VDC DC power supply by hooking up the secondary as primary on the AC line.  It worked, but the output voltage dropped off rather too much at higher current levels.  I don't know if that was a consequence of the type of transformer or the regulation circuit.

For an automobile application I suspect that the lower cost of the 60 HZ transformers might tend to make them preferable.  But the aircraft power supply may be designed to reduce weight and have a higher operating frequency.
