OK, so we are choking the high impedance signal into the capacitors as a secondary circuit and we have a low impedance signal going through a resistor in the primary circuit.
Been playing around again and found some very interesting observations indeed, when i've compared my own circuit with Stan's there are common denominators and trends. So here is basically in a nut shell what happens.
Stans secondary is capable of producing 100v and no more than 1.25 amps of current. His primary circuit uses 450mA into the 220 ohm resistor at R1 at the lower impedance value, the choke circuit is passive at the gate frequency.
At the higher impedance value which we are going to choke out of the primary circuit the reactive chokes and the reactive core sap another 625mA out of the full 360 degrees of one pulse.
In total, the primary resistor and the total reactive inductance cost the secondary 1.075 amps. Because of the diode D1, only the magnetising current of the choke is shown back to the primary impedance and the value of the capacitance dump of the choke is left as an unknown as far as the primary is concerned.
My system, it turned out that I had 1 amp available from the secondary, my primary resistor was 300 ohm and consumed 500mA, my chokes were 200 ohm reactive inductance and also consumed 500mA. I was too close to the limit so my primary resister had to rise to 320 ohm on my variable so not to stress the secondary.
So here are the definate rules:
1. The primary circuit resistor and reactance of the choke at higher impedance must not exceed the output current of the secondary.
2. The primary circuit resistor value is determined by subtracting current from the reactance of the choke from the current output of the secondary then not exceeding it.
3. The current of the chokes reactance is determined by subtracting the current of the primary circuit resistor from the available secondary current and not exceeding it.
