Hi,
OK, here's my Saturday's project. I posted a "Power supply
circuit.pdf" in the files section of this list.
It wound up being different than what I started with. Sensing current
was too crude. Instead this circuit compares the power supply voltage
against the xformer secondary voltage. It pulse width modulates the
dump resistor and has a very nice proportional response. The PWM goes
from 0% to 100% as the power supply voltage climbs to 2V above the
nominal voltage. It has been tested and works very well.
