- Here is the promised prequel to the demonstration video. As promised, the video shows the schematic and design of the modulated circuit. This circuit is a beast, I was able to approach 300 watt output on it (see my demonstration video • Overpowered modulated ... )

I highly recommend you check out www.geekcircuits.com , a lot of useful schematics including the modulator I am using can be found there.

The purpose of the Slayer exciter circuit was to make it an easy entry point for hobbyists to build their first Tesla coil. You are a very talented electrical engineer, but the complexities you construct have pushed it out of reach of the average hobbyist. It would be great to add snubbers to the Slayer without ICs, gate drivers, modulation, square waves…etc etc etc. Nice video!
interesting design. thanks for sharing
I'm glad you like it! I will experiment further with this design, perhaps making a resonant half bridge with irfp460s which should in theorhy double the output power for a given voltage as the high and low states will now be driven instead of just the high state and I will be able to run it from mains. I'll keep the modulator circuit though and use maybe an igbt to modulate the circuit. I'll make a video about it eventually too when I get some free time.
@@ivanrodionov9724 the only set back with the half bridge is the need for higher input voltage. symmetric power supply. But yes, then you can use AC from the wall, rectify it to positive and negative DC.
@@MasterIvo I was gonna get back to you, but I was under a rock for the past month cause of Uni, so sorry I am replying late.
For a DC load, a half bridge supply will give half the voltage per cycle instead of full and full voltage, so the power of the signal will indeed be lower as it is proportional to the square. I am unsure if this is true with an AC load close to resonance however, as weird stuff begins to happen around resonance. Going with mains voltage certainly is a good idea.
The main problem with a bridge circuit is throughshoot which frankly is a pain in the ass to deal with especially at high frequencies. If you go with a half bridge circuit, the main advantage is simplicity and only throughshoot can occur, whereas with a full bridge you need to adjust the phasing just right so that you don't create a short and cross shoot. Trouble is, the frequency of the circuit is dynamic so some fancy tricks will need to be used.
TBH, if you have any ideas on how to create a system that can dynamically adjust phasing, I am all ears.
@@ivanrodionov9724 almost missed your comment. but saw it! phasing is still a mystery to me. I also have weird phasing effects around resonance. as if the fields push eachother away. so balancing the field strength would be key (maybe)
the through shoot is what I am using in my experiments, as it sets up displacement current from the rapid change in (high) voltage
Very good one... Different one...
Thanks for sharing.
Thank you for watching. I do believe this is the first digitally modulated Slayer Exciter like circuit on youtube. Maybe sometime in the future (ie after exam season at Uni) I'll soup it up some more.

Can you mention ur mai id? Had some follow up questions to ask
Hello! Questions are always good to ask and thank you for your kind words :). What ID would you prefer?
@@ivanrodionov9724 ur mail id would be fine😇
If you want a lot of views do a EMP.
That's an idea!
@@ivanrodionov9724 I have you the blue print all you have to do is execute.
@@caseyosborne3148 Sure! I'd love to have a look at what you got! Do you use a discord/email/whatever else?
@@ivanrodionov9724 Instead of this, move on to a push pull feedback topology similar to the Skori/Tefatronix. Channel Magneticitist has good examples of these circuits
@@sFeral hey! Thanks for your reply! TBH, much preffer bridged designes over a push pull design as these tend to be easier to build. I might however eventually tr making a push pull design using a center tap coil. Thanks for the recommended channel's I'll check them out.
