I love the well thought out calculations ! .... Why have you not got more subscribers ? 🧐🇬🇧🤔👍🏻🤓🤓🤓❤️❤️❤️🧠🧠🧠

After searching for hours finally got a proper video Thank you

Wow, great video! Really liked the indepth look at how to drive these things, it's refreshing as there's just so many braindead videos on this website by people who don't tell you about their failures and upload a 20 second clip with no explanations.

To figure # turns on xformer ive seen folks put 1 volt on the primary and measure the secondary. Love the videos!👍

I love your explanations, great channel

Both parts were great, Thank You!

Your presentation very professional ! thank you for your commitment !

Very informative amd Helpful video ❤❤ please make a Video of Oscillators

Very good explanation.

wow great videos. you give me inspiration to continue making my own videos . thanks

great job keep sharing ur experiences god bless u and all of us

Thank you this video really helpful

Your cat is literally so cute ! ^^ many thanks for sharing the knowledge, that's the best ever 😃

make a resonant oscillator on irfp250 mosfets to power it I built a ZVS powering 3 transformer transformers and get a thick 17 centimeter arc with 34V DC power

Answered alot of my questions from part 1. Have u ever converted a crt to crude oscilloscope? Do you know of a way to protect my cheap amazon scope from destruction when analyzing drivers?

I wonder why the heck you have only 11k subs.....you deserve More.

Thanks for your videos and details how to drive FBT. I have a BSC 25-0278Q and I wanted to drive it, creating some sparks, like you did in the previous video. I like to make an a "universal driver" that I can use to drive FBTs and other projects. But it seems to me that lot more goes into the driver than I understand and the idea of an a "universal driver" isn't gonna happen - right? Also, when I was trying to determine where on my FBT is the input, I'm getting very small values in Ohms between pins; example: 0.28, 0.33 and 0.10 Ohms. BUT when I included the yellow wire against the pins, I get values in Mega Ohms; example: 7.623 Mohms to several pins at the bottom of the FBT. Do you have a better ways to determine where is the primary and secondary on the FBT? Would you be willing to answer some questions using Skype or some other form of a video call?

Great video. Would an isolation transformer driving the power transistor reduce the switching speed?

The negative spikes (impulses) you killed by putting a diode is the key to the Zero Point Energy production. The rest of the experiment was not important. All MOSFETs have internal "Body Diodes" putting one externally is a double protection. I am more into ZPE than producing longer and stronger arc. Keep up the good work.

Its really sad when you come to think of it, most people into high voltage have no idea they are tapping the quantum vacuum and zpe.

@@ThatThing1675 is that why when you measure electrons they get more random? Youre introducing something into their zero point energy field. So they flow around it. Energy flows in the least resistance.

The body diodes in mosfets don't protect the transistor from the initial voltage spike. Example: an N-channel mostfet is used as a low side switch so the inductor is connected to the high side, when the transistor turns off the inductor will supply a high positive voltage to the drain of the transistor. But the body diode have its cathode connected to the drain so it can't protect the transistor against the positive spike. However if no external diode or load is connected to divert the positive spike, the field will collapse fast and the positive spike will rise very quickly and then fall even faster. When it falls it goes to a negative spike very briefly and this is what the body diode protects from. If you put a diode to divert the positive spike then the negative spike won't happen. So your saying the initial positive spike is what gives ZPE or the second negative spike?

U need more views on this. Add "reverse engineered" to the title. Nicely done.

I'm trying desperately to understand your video here. You say you have two turns for the primary and the feedback but I see there appears to be more than two tuns around the core? Apologies for the dumb question. I have exactly the same components, I know my flyback works, I'm running 12V 5A power supply, maybe this is no good? Any advice will be much appreciated.

It’s not a dumb question, I caught that too. The dumbest questions are the ones never asked

I have collected 3 flashbacks. I want to make an HHO cell and Tesla coil. I collect CRTs off the side of the road. All in working order. There's one sitting two houses down and it's a nice one but my wife is tired of me bringing them home. So I need to get these built so I have a reason to get more.

I made a monster ZVS flyback driver circuit myself without an oscilloscope, it's NOT necessary but convenient.

Best voltag

How to get 20 kv on flyback with 2n3055 as driver?

6:45 to measure the turns ratio, put a low voltage sine wave, at the working frequency, into the primary of the transformer, and measure the voltage at the secondary. This gives you the approximate turns ratio.

Maybe you can help me out. I have a flyback driver that stop working properly. It keeps blowing tip102 transistors and my tip35c. It never did that before. If i connect it to my zvs. It works fine.

Sounds like the flyback is stressing out the transistor making it more prone to failure. This is usually because of inductive spiking, but sometimes it can be because you are improperly driving the gate, leading to overheating and failure. If you have an oscilloscope you could do some investigating

@@goobman1981 well I demonstrated using a diode and a capacitor in the video to help deal with the inductive spiking and transient voltages the transistor was experiencing, the type of switching circuit is important too, I cant give you a solid answer because a lot depends on the circuit. If a transistor keeps failing even after you put on protective snubbers, caps, and diodes, then just use a better transistor.

😊😊👍🙏🙏

I am worried for your cat 🐈 because of your safety considerations in your lab

You know you can use a light box to drive the flyback Transformers

what exactly is a jellybean transistor? how is different from other transistors?

how to protect the transistor to not put the transistor in fire you can make a video on it

Those transient voltages killed my Transistor

Those transient voltages were never fully addressed, driving an inductive load, I would recommend a diode across the collector and emitter. They are often employed internally in many IGBT, and mosfets….even in some transistors while driving inductive loads. Inductive reactance is something to consider also, it’s one thing to measure resistance of the coils, but as another person suggested instead of resistance drive your base with 1Khz or 10Khz etc… frequency signals, and compare the Vin to Vout to determine turns ratio. In any pulsing circuit it’s much more accurate. It’s ac electronics vs dc electronics, even if it’s pulsing dc. Sometimes his method can give a very rough idea, I often did it for a rough guess in lower f circuits, but I prefer the textbook method especially for higher frequency circuits.
