An update on what I am working on, series switching MOSFETs, close and loose coupling, auto oscillating relays and Tesla oscillator article July 1919 Electric experimenter explained.
Sadly the C3M 1700V mosfets do not exist (yet?) so the max is now 1200V per mosfet.
But there is a C2M 1700V that can be used. Only it needs +20V - 5V for switching properly, so it needs a different isolated dc dc converter.

See links in the video description! The C3M 1700V SiC mosfets do not exist (yet?), but there is a C2M 1700V MOSFET. it only needs a higher gate voltage (+20 - 5 volts). So to use it you will also need a different isolated dc dc converter.

Super interresting as always! Keep up the good work! I follow alot of people that are into tesla's works. You are by far the most interresting, true and clear person to listen to on youtube. You seem to be on the very same path that tesla has been through... There is no other paths anyways i think, but you are maybe thinking the same way he did! Thankyou for sharing!

I thought I watched all your videos so far but it seems I have not managed to yet. I find myself repeatedly watching your videos so that I can better remember them. I started copying some of the diagrams down by hand awhile ago in one of my note books. now that I'm free I'll be able to continue doing it. I have this idea I want to test using asymmetrical capacitors and bifilar coils involving constructive and destructive frequency by sending aetherial perturbations beamformed at each other to a conductor in between.

Hi Master Ivo. The reason I mentioned using mechanical switching by Tesla before is twofold. First is the parameter of mosfets called "ON time" which means how much time the mosfet takes to open its switch. If it was instant, suppose, you would get the full power "cold electricity" we seek. Unfortunately when we read a mosfet's or any transistor's spec sheet and see the value or graph of the on time, we see that it is far from instant and the resistance when it turns on takes time to dissipate, which does not allow the full power of the tesla energy to pass through. Secondly, the gains we want in the output power or watts can only be increased to the efficiency we desire with increased voltage pulses if VxA=W because more than a few milliamps are not only hazardous but also take their toll on hardware. So dear brother, these are the two reasons and I could not explain them in my previous message. The voltage has to be incredibly high. It is precisely why Tesla's gigantic pancake coil we see in photos have the windings so far apart, so the current can not simply jump across the coil. Since you have the time and motivation and the grasp over the subject I am always eagerly following your works, sharing my thoughts and wish you continuing success.
@MasterIvo
@MasterIvo 3 жыл бұрын
thank you for your thoughts. for me, the turn of time of the mosfet is most important. as I do not discharge a capacitor, but a coil. the gain is not directly from the impulse, but from the secondary effect of the voltage impulses on the current (in parallel resonant L3). This current gain in L3 is then feedback into L1.

Awesome I've been studying series and paralllel mosfet banks. Too bad there's no details on the series mosfet. I could see you had the gatedriver output side grounded to the source of the mosfets which is necessary. I'm supposing though you had to float a power supply but where is the isolation transformers? Usually there's a dc-dc converter that does this like rd001 or rd002. But maybe thyristors are cheaper for a large bank. The mosfets are supposed to be faster switching and have less losses.

magstar.eu/mosfet has what you need (free). I use an isolation dc dc converter (on the bottom of the pcb). Important for series mosfsts is to match Vg threshold (threshold voltage where the gate turns the mosfet on)

@acidbyte4760 Жыл бұрын
Have you considered a bootstrap ic for the gatedrive? A driver like ir2110 can be used(they can be found with higher voltage specs). Because you can switch both the lowside and highside at the same time. Advantage of this is that the outputs are matched in delay. Though i like your design too! It could be that the diodes get warm because of the material differences between them as no component is truely the same. Matching their performance could help eliminate the heat :)

Cool! The cap switchboard is easy. take 30 switches, and 25 caps 10 of 100 pF 10 of 1 nf and 5 of 10nF all must be able of high voltage (1000V DC or something like that) and polypropylene, like the wima fkp1 or mkp10 series. place every thing in parallel. the switch connects one leg of the cap or opens it. sum all connections to the connectors (two). This isn't perfect! always use as much capacitors at the same time as possible, to reduce the load from the impulses. and once you have something working, measure the capacity and replace it with a equal capacitors (several parallel) without switches. check if they don't get hot.

@@MasterIvo cool, got caps, thnx rockstar! you ever notice toggle switches themselves heating? guess we'll learn "empirically" if specs matter much for on/off switch at 50kHz :) for symmetric power supply, to summarize: so we want dual channel bench supply (two 'ZK-4KX' buck-boost converters side by side on acrylic panel, w/ 4 binding posts!) series connected in the middle, to yield matching +/- bipolar voltage to power the back of circuit, which we can slowly sweep higher from ±1V to ±5V but likely no more than ±10V, while dual function generator pumps in the 49% inverse sine's to front of circuit (with separate 12v 1A DC in)... hypothetically with a rigol 1054z and probes able to not melt from however many kV from L3? And current limited to 1-1.5A for each +/- rail? i picked up 4 MKP10 680nF 250V caps, 2/parallel for (+) and 2/parallel for (-), from bench supply, earth ground in middle, to finally power the 'meat' of rad°hb circuit - seem practicable? i believe i almost grasp the 'workflow' hopefully, if i squeeze brain hard enough, hrrrrmmmmfff!

Great! you're getting there! caps sound good. More input voltage will be welcome(2x24V, I use 2x 32V, 3A per channel is enough headroom). buck boost in series could work but better to have them balanced (with feedback). out of phase Signals must be square waves not sine. If L3 is crazy high voltage, just load it down with resistance (or use high voltage probes, I use pintek, 8kV) And yes always slowly push the voltage up. first tume it on lower voltage ratings then slowly push it up.

I should have known, buck boosts are usually bridged negative & ground, so I'm only able to get positive volts unless one buck boost has positive grounded & other has negative. I learn ^ after finishing build :) instead, for adjustable symmetric power source (+/0/-), im going with Tekpower TP-3005D-3 triple output linear supply with built-in series/parallel modes & tracking so I dont have to work 2 knobs for voltage sweep. Insane/unsustainable/lucrative USA Covid unemployment benefits allowed me to pick up 2 pintek hvp-08's, and Rigol DS1054Z scope (which costs less than the probes lol). Can't find Pinktek PA-655 but it looks like PA-622 might be able to handle the task(?), 200~300kHz bandwidth instead of 500kHz, similar specs otherwise. want FLIR thermal camera to monitor board temp effortlessly. will put pix of cap switchboards on instagram soon! first one ugly, second one sexy. uses tinned copper 'buss wire' with clear silicone conformal coating & acrylic base of course. much love

So Master Ivo what you mean by the diagram in fig.1 that Tesla was causing a pulsed resonance self-excitation on a first Ac circuit by generating a high voltage on a solenoid becoming self-excited and then he rectifies this AC voltage which then becomes a pulsed DC by inserting a capacitor in series in front of the second primary so it's not a standard self-excitation that is caused by an AC circuit but a pulsed DC that resonates in the second primary and secondary circuit...It's because of the capacitor that it's different, did I understand correctly? Thank you for your extraordinary work IVO, you have a powerful consciousness !! 😉

with AC it's more complex. its easier to understand with DC. If mains 50 or 60 cps AC was used, there would be many DC operations per half cycle AC. the relays was pulsed, while the series resonant primary coil was IMpulsed. setting the secondairy in its special kind of Tesla resonance

Did you ever read about NMR (nuclear magnetic resonance)? please take a look here www.free-energy-info.tuks.nl/McFreey.html I think this info can be a key in special energy effects. the resonant/oscillating coil is also vibrating mechanically, so do the copper nuclei with their spin, thus interacting with nearby fields and electrons (normally the geomagnetic field is the basis, but a permanent magnet nowadays have a lot more energy density). Somehow this could transform matter into energy but may also cause radioactivity. just be carefull by exploring this. Dont oversee that the nuclei can be vibrated electrically instead mechanically/magneticly... just read and get inspired by the paper ;)

when the coil is turned off, the build up magnetic field energy starts ringing at the resonant frequency of the coil (much higher frequency). When a series resonant coil is connected to ground it can discharge through it amd will stop ringing after a resonant half wave (=the impulse). by directing the energy away from the opening switch the relays will last much longer!
