I would like to replicate this experiment as faithfully as possible. Unfortunately, my knowledge of electronics is too limited to do it on my own. I'm counting on the help of forum users.
I jumped to the conclusion too quickly that a Royer oscillator was used in the video. Perhaps it's a voltage boost converter or a different type of oscillator? I'd like to use the circuit that was most similar to the one used in the video to power the green transformer.
I have a very similar transformer TH41-220-50 with leads arranged in the same way as in the video. In the video, the circuit of the coil powered by high-voltage pulses from the transformer is not galvanically connected to the circuit of the green transformer with the light bulb. Both of these circuits are only powered together from a single 12V battery.
The voltage measured at the output of the green transformer is before the diode, after which there is a light bulb, and it's 100V. The light bulb is not connected to the secondary winding, only to the primary winding. I'll add that the secondary winding of the green transformer is not used. That is, one pin of the primary winding is connected to one pin of the secondary winding - why?
The circuit of the green transformer contains two transistors, a microchip, a choke or an electrolytic capacitor, two large electrolytic capacitors, and probably a potentiometer.
What type of oscillator could have been used to power the green transformer in this experiment?
I am attaching the datasheet of the transformer I want to use for this experiment. It is a TH41-220-50 transformer. The datasheet is included as an attachment. Below are pictures of the elements used in the circuit of the green transformer.
Regarding the questions:
"First you must decide whether you want this energy transfer to happen by conduction or by radiation.
In case of the latter, you also must decide whether you want this energy to be transferred by the E-field or the H-field or both."
To begin with, as in the video, through radiation. Next, we can try through conduction. Transferred by the E-field
"Firstly, this oscillator requires a center-tapped primary winding and feedback winding. Do you have such windings ?"
What do you mean feedback windings?
"If the 50Hz signal from the green transformer is the phase-determining component then you can use the signal from its Royer feedback winding. When the voltage signal across this winding gets low, then this is an indicator that the transformer's primary current is nearing saturation (and its peak) and then you can use a comparator, such as the ubiquitous 339, to signal the opening of the primary winding of the LOPT in order to generate the HV pulse at its secondary."
What is LOPT? Can you provide an example schematic where the 339 comparator synchronizes two signals?
