That falstad link shows that with a resistor,capacitor,diode system plus a low duty cycle oscillator I can turn one power supply to more than one power supply, but it has a ripple to it.

The oscillator charges the caps and then they release independantly and they are protected from back discharge with the diodes, so it seems like it should work to me at this stage.

I think it does short between the separate supplies for the instantaneous moment the oscillator is charging the caps, but its only for such a small time period you should get away with it.

So you just short the oscillator to the caps is the best with as least resistance possible.

Note I had a problem with the circuit, it did short back through the diodes, but if u use the negative cycle to block the diodes on the off period it fixes it, stops the short.

Its not complete rubbish, it actually lets you designate amps at any resistance!

Pulse width modulation isn’t designating ‘any’ amps at ‘any’ resistance.

If u can supply 10 volts, 1 ohm at 100 milliamps, then u know what im talking about.
