Kapanadze Cousin - DALLY FREE ENERGY

Hi Void,
here the screenshot of that setup,
yellow is across the 25W / 220V bulb,  one side grounded
blue    is 5cm away from the antenna
Only the Kacher is running at 25V
Regards itsu

Many thanks for that Itsu! It is helpful to have a comparison.
Next step I will have to test with a battery instead of a bench power supply to see
if a ground loop has been affecting my results.
All the best...

Jeg,

I have found that any toroidal choke around 100uH or higher will work. The choke will prevent the Kacher pulling too higher pulse current and diverting current from the push-pull / PWM. If this choke is shorted, the load bulbs will dim noticeably. Below is a scope shot of the waveform taken on the cathode of the series diode to ground after the choke. The critical bit is getting the Kacher frequency tuned for the maximum effect. In my case its around 950KHz. Where have I seen that frequency mentioned in past posts?

Hoppy this choke doesn't have to be common mode? How you prevent the HV return? I think your series diodes to act better if anode at 24V clean dc instead of ground. They will send back to the source anything below 24V.

Jeg,

Common mode choke does not work for me. See previous posts.

Hi Hoppy. I think some people have reported a grenade resonance point around there.

At katcher side did you disconnect the 1000uF cap after the choke or you didn't have any with so much capacity?
