SSTC pt. 13 - Minimizing stray inductances

[@SamSpiri]

Thanks for routing for dummies! I was missing that information for a long time

[@noelj62]

good points that are applicable to any amplifier circuit not only Tesla coil circuit.

Incredible, this is also applied in antenna coupling. Forgot to thank you Sir! 👍😆

worth it... thanks for the information 👍

Daniel: today let's talk about stray thing like stray inductance , resistance , etc. Cat appears* Daniel: wait you are not stray!!!!😒😒😂😂😒

Thank You for sharing your Valuable Knowledge

[@nightrous3026]

Wow not only did you make a decent SSTC from scratch, but your even OPTIMIZING it to go even. FURTHER BEYOND!

[@1pcfred]

There's always a lot going on with PCB layout. I remember building a stepper motor driver once and having a connection on the wrong side of a filter capacitor made the circuit not work. I was looking at it thinking, nah it couldn't be. But as soon as I cut one trace it worked. The control chip was getting back EMF interference from the motor coils and it just wouldn't work the way the circuit was routed initially. The cap had to be there to soak that noise up.

Love your cute cat!!! I have 2 of them myself, the black one was found by me in my back yard early 2014, almost dead kitten. The big male came from the neighbor, who could not take care of him. Anyway, they have their own room and 2 windows a tall playhouse/scratch pole and ramp..... They love it there and sometimes they don't ant to go to the rest of the house. After all, they are cats and we are in their way! ha ha ha

[@fangtie_experiments]

Good video，nice and clear explain of the MOSFET gate driver circuit

[@leozendo3500]

Well done. Finally, some good engineering taught to enthusiasts. For example, there isn't any video teaching soft-switching or ZVS/ZCS technology to HV hobbyists

[@electronic7979]

Helpful video 👍

[@jasonwarbird]

Thanks for this!!

[@noelj62]

yesterday I was testing a cheap 12V fan without clamping diode connected to same supply as an LED strip. Some LEDs got damaged instantly due to back EMC from the DC motor. I guess it's a real life lesson to be learnt.

[@Gameplayer55055]

Nice a bit educational videos

[@LucasPereiradaSilva]

There's a lot of black magic going on in high-frequency circuits...

[@godfreypoon5148]

It's only black magic until you understand why. Then it's just like everything else. Just think, if you didn't know how electricity worked at all, you would say there was a lot of black magic going on with electricity.

[@ornessarhithfaeron3576]

Electricity *is* black magic fuckery

[@akshaykumarvyas]

I have some questions : Can we use EE cores for GATE DRIVE TRANSFORMERS? Does the AL value have to be high for the ferrite core? Should the ferrite material be the one used for power transformers or for inductors?

[@robson6285]

Indeed i want to know that too!

[@DiodeGoneWild]

For a GDT you can use EE core with no air gap.

[@akshaykumarvyas]

@@DiodeGoneWild what about the ferrite material choice?

[@robson6285]

@@akshaykumarvyas indeed too! Can you give us some of that knowledge too?

CAN i use that sircuit with dc Instead of half Wave ac?

[@creblabo]

Cool Video

[@Electronichub_05]

Very interesting 👍

[@uK8cvPAq]

I knew about current paths but it never occurred to me to run the gate and source/emitter traces next to each other which is odd as I always twist pairs when using gate drive transformers. How do you make sure the oscillator and chip support components don't capacitively pick up noise from surrounding traces and components?

[@smartchip]

Thanks, good video,

[@jawjuk]

Is that conventional or electron flow for the hand rule...?

[@gordonwedman3179]

My textbook: " grasping the conductor with your left hand with your thumb pointing in the direction of the current your fingers indicate the direction of the magnetic lines of force". Is different from what you are saying?

[@DiodeGoneWild]

You're probably talking about the Fleming's left hand law, which applies to the magnetic force direction. I used the Amper's right hand law which applies to the direction of the magnetic lines around the wire.

[@gordonwedman3179]

@@DiodeGoneWild yea, I was not sure if "magnetic force direction" was the same as "direction of magnetic lines" . A bit confusing.

[@redstoner2006]

can i use coax cable for this?

[@magnumopus9058]

You said you would do a video on the power strip you use to measure current devices use. I cant find it if you did that video, if you didnt, when will you do it

[@noakeswalker]

"Don't grab a live wire to use the right hand rule" - haha - it's a shame that these days, you have to actually point this out in case it's not obvious to everyone....

[@fifififi9959]

I shared the driver and emitter connection, trace was poor, so it broke under high current, and this disconnected the driver, which managed to burn both transistors :(

[@ats89117]

Nice video, but it seems like putting the gate driver much closer and the capacitors a little further away would have been a better choice...

[@ats89117]

@G E T R E K T 905 Minimizing inductance between the gate driver chip and the gate pin is critical as this inductance forms a resonant circuit with the gate capacitance potentially causing overshoot and oscillation which can blow up the transistor or the driver.

[@ats89117]

@G E T R E K T 905 Putting the small gate driver next to the power MOSFET significantly reduces the inductance and associated resonance problems. The large capacitors already have significant internal inductance so putting them a little further away doesn't affect them much. As an aside, the gate driver can source or sink a fair amount of current for a short period of time. The IXYS gate driver I use sources or sinks up to 14 Amps to start the turn on or turn off process...

[@johnkubik8559]

The problem you're facing are not so much stray inductance but propagation delay in transmission line. When you bring closer the the source and return path, you increase the capacitance between them and lower the line impedance, the only thing seen by your source on a fast raising edge, lowering the impedance send more current on the cable, which is what you need when attacking a purely capacitive load such as the gate of a MOSFET. The return current generating a magnetic field will only occur when the wave has travel the full length of the cable and is returning, in copper expect about 2ns per feet traveled after what the conventional laws of steady state apply. When the source and destination impedance don't match you will experience a return voltage or current, the standing wave phenomena.

Is the like and comment from patreon

[@drobotk]

Yes

[@psycronizer]

yes, old crazy voice is right.....if you want to get some other good examples of how to properly mount your components, take a look at any circuitry that deals with frequencies anywhere over two gigahertz....amplifiers and filters are good examples

[@NavnitBhimani]

Use twisted pair of wire will be more better

[@the8bitpc_805]

Hi man, your videos are consistent with what you are doing. As we can see, you know most things about electronics. But this pronunciation is really catastrophic. For example, instead of "others", you say something about the "udder", instead of "two" you say something about the "tune", etc. So I wish you the best and try to work on better pronunciations.
