Today i made an experiment that proved the theory about recirculating current to be true.
I used a signal generator and inductor made off 20 awg wire with an antenna ferrite inductance of +-220uh and two 1500v 68nf capacitors in parallel. A small toroidal transformer I made for this test had 200uh primary and 70mh secondary. Hooked up as on the simulations i sent to you.
The result was i got 100v with 2 amps recirculating between the components
input current was mili amps and strangely my mosfet heat a lot.
Frequency was 27khz
I tried to hook a microwave capacitor too resonant frequency was 10khz but voltage was about 40v and amps remained the same.
As i stated on the first post the current recirculating depends on the frequency and capacitance value. So for an inductor with determined Q factor you will get different voltages if you change the capacitor value and adjust to the resonant frequency.
So thats why i'm going to use thick wire for my resonant coil to have a high Q factor.
Remember
If i lower the inductance value i have lower voltage, higher frequency, and higher current.
i will construct this week a better output stage for my signal generator pll ... Maybe with bipolar transistors.
Does any of you know how to make a 3 stages or 4 stages amplifier to handle up to 40 amps? This is to have very low losses.
Thanks
