I'm building a circuit that needs 3 voltages.
15ishVDC to run a small motor
90ishVDC to run a large motor
and 105ishVDC to fire the high side MOSFETs that control the 90VDC motor.
My question is this... can I generate these three voltages from 2 transformers ?
I've got a small 10VDC transformer and a large 60VDC transformer.
Can I connect them in series and tap 10VAC for the small motor and 60VAC for the large motor and 70VAC for the MOSFET supply ?
What if I built a voltage doubler from caps and diodes that got me 180VDC and then I used a voltage divider to drive the high side MOSFET ?
Thanks.
