Doing stuff at Resonance
Hi all,
I have been doing some experiments with resonance and found out that charging batteries in series is interesting:
nilrehob - YouTube
Now, I have another idea, but unfortunately I don't have any suitable parts available, I have to find some somewhere and it will probably take some considerable time. But I'll let You know so that if you have the time and parts You can try it out.
1) Hook up all generator-coils in series to create a HV source. We just want the voltage and very little current. The higher the voltage the better.
2) Get all AC caps You have that can handle the voltage above and put them in parallel. The higher the capacitance the better. The lower the ESR the better.
3) Make an external-coil that will be in resonance with Your caps for Your favorite frequency. The lower DC-resistance the better. I guess air-core is best to avoid saturation.
4) Get a FWBR and a battery to charge.
5) Connect the external-coil, the cap and the FWBR in series. This will form the resonance-tank charging the battery in series.
6) Have an optional switch across the AC-legs of the FWBR.
7) Connect the generator-coil across the cap in series with a resistor.
8) Tweak ;-)
