New DC resonant charging circuit

[Login to see usernames]

add a series resistor some where? might need a big one though

a coil perhaps as resistor?

Why is it that current goes up dramatically if i put a flyback diode anti-parallel to the coil in this circuit?
Same is when i put a diode parallel to the transformer, the current isn't frequency dependant anymore, without diode: 30V / 0,3A. with diode: 3V / 1A (1A limit from power supply). i don't get it.


anyway, problem solved. without the diode current draw is small.

here a new Stan based setup.
The voltage across the cap charges higher then applied voltage.
The resistor is for leaking charge, but cannot simulate a WFC perfectly...

Cap and coil and frequency match.
The result is that amps and volts are 180 degree out of phase.
Hmmm, who said that his system was working with 180 degrees phase difference between volts and amps?
yes STAN MEYER...

Why does it work in a simulation but not in reality

Brian,

You added an Antenna towards your schematic.
Can you explain why you did this?

Steve
