hi everyone,
I thought of this circuit last night. It's an ordinary LC circuit with feed back. I will build the circuit later but I'll put it up in case anyone interested.
Introduction:
After seeing the video posted by gotoluc on the effect of BEMF being recirculate to coil, it is fascinate to see the reduction in amperage drawn when the recirculation line is shut. It is logical to assumed that the effect only occur when on recirc. By looping back the current through diode(DC) or oscillate them through capacitor(AC) should be of similar effect. The reduced drawn current is suspected to only compensate for the coil ohmic loss and diode loss (cap loss in AC). If in fact this is the case, then the LC loop operating current is independent of the source drawn current. This circuit design contain a feedback to extract energy from the LC loop. If the theory is correct, it is capable of self substain once loop current exceed drawn current.
Circuit description:
A bifilarl wound coil (prefer 1:1 ratio with same gauge) is set up so that 1 line is connected to capacitor C2( of high voltage rating at low capacitance) forming a LC loop. The other line serve as feedback connected to C1 via a full wave rectifier. A LED is connected to the feedback to monitor the rate of energy depletion, or increase in energy if self substain. Drawn current is circulate through the LC loop passing a high speed switching mechanism.
Theory of operation:
When C1( prefer high capacitance) is charged, the switching mechanism is set to work providing the initial energy to the LC loop. Once the loops operating current capacity is reach, the drawn current is reduced to just only compensate for the coil ohmic loss and capacitor loss. The loop current in AC form is independent and different from the drawn current, therefore, assuming the transformer operation is ideal, the current induced is the same as the loop operating current. This induce current cause higher induction in the LC loop and subsequently, lower the oscillating frequency. If the feedback current is less than the drawn current, the LED will be dimmer. If it is self substain, then C1 will continue to charge up show by brighter LED.
