Lossless Impedance Matching - Part1/2

[@alaricsnellpym]

This is a fantastic explanation! Amateur radio people building antenna matchers should watch this :-)

[@patrickoneillnl1966]

As I am just getting into HAM radio, much is still new. However, I have watched several of your videos and love how clearly you explain concepts and go through the trouble of simulating the circuits and building and testing an example. Thank you!

[@kennymanchester]

The very best series on impedance matching theory and practice I have found online. Thanks so much for this work.

[@jamppap123]

This video was sooo good! I learned better from this video about impedance matching than at a university :D

[@johnwest7993]

Excellent. Finally a clear explanation of impedance matching, and in under 21 minutes, too! I'm putting the link to this video in my Favorites. Thank you.

You can use Smith chart to design these circuits without the use of equations :-) It's with adding that these circuits works well up to 1 GHz. Above that it's better to use eg. matching stub.

Excellent presentation. Looking forward to part2. Thank you.

[@johanneslode2006]

Great explanations to come to T- and Pi-filters. You made my day. Thanks.

[@cristianoferreira7842]

Your videos are gold!

[@shijuk8478]

Simple and Clear ✌️

[@dmyegorov74]

Thank you very much for your work.

[@Projacked1]

Super cool video; going into my favorite list at once.

[@M0NTVHomebrewing]

Very good, clear explanations. Thank you.

[@plinsburg]

Ok, I got it. Open Patreon, click on support. Thank you for the video.

[@vicafrederick3386]

thank you for the comment in the description on the typo!

[@FesZElectronics]

I try to add comments to correct any mistakes I find too late... its not a perfect system, but its better than nothing I guess

[@waterfuel]

Help needed! How do I match impedance of inverter16v AC output SOURCE to 16vAC isolation transformer primary, that I have to hand WIND, for 4 ohms load of 32v AC 6 amps secondary ? Do I use the ohms of primary 16v + 12 amps division or the resistance .06 ohms of inverter output contacts terminals at 20khz frequency? Voltage and turns ratio same as 1:2. The online formula for inductance value of turns requires reactance value in ohms , at the frequency of source.

[@markusberg2770]

Excellent topic.

[@ertugrulirgat6197]

Good rf video tanks

[@biswajit681]

Could you please show simulation of 3 phase BLDC motor simulation in LTspice

[@curtstacy779]

Perfect timing of your video. I was just working on this. excellent job! If you could add a little? on the RF amplifiers, they are using a transformer as part of this impedance matching on input and output. could you explain this? I bet you could clear some confusion I have on this.

[@FesZElectronics]

Transformers will add galvanic isolation, but also can be built to work over very wide frequency ranges. So for example a transformer used in audio to match the output impedance of a vacuum tube (~4Kohm) to a speaker (8ohm) will work over multiple decades of frequency. At some point I do plan to look at transformers for impedance matching also.

[@curtstacy779]

@@FesZElectronics Ok that explains my confusion! that's great and makes so much more sense. I need to look into the wide bandwidth circuits for that application. I am working with both at the moment and I was getting confused. Thank you so much!

[@curtstacy779]

Thank you Fesz for getting me started on the right track! and your excellent video! I am leaving this link so that if anyone is confused by the broadband impedance matching it seems to be a good start. video 6 and 7. kzbin.info/www/bejne/hImZeGx3Z7pqoa8

[@maksymkloka5016]

Fantastic. One thing though ... is your Excel equation for Lp correct? Could you double check. Qel seems to be in demoninator.

[@Steven_Bennett_YT]

Your videos are excellent, now I understand the things that confused me at university! Would it be possible to add links to download your LT-Spice simulations so we can reproduce your experiments? If so thank you.

[@FesZElectronics]

Hello Steven. I have all video related files like simulations, but I share them only with certain tier Patron Supporters as a special thank you for their support.

[@Steven_Bennett_YT]

@@FesZElectronics I understand - thank you.

[@lastnameavailableok]

awesome

[@R2AUK]

👍🔥

[@TanukiTakey]

Can we get a link to the spreadsheet shown early in the video? Maybe a google sheets version? Thanks!

[@FesZElectronics]

I will add it in the description of part 2, since more sheets get added - I want it to be a single document with all the various worksheets inside. Part 2 is the next ep this Sunday.

[@bhadreshthakkar3447]

Hello... Nice explanation Can you please share the excel sheet.

[@FesZElectronics]

I linked it in part2, but I guess I'll add it to this part also

I appreciate these videos tremendously, because they make right to repair much more accessible to the average person. But as far as video production goes, this habit of having the video as hundreds of little tiny videos that are put together is starting to get on my nerves. It takes far too long to produce a video like this, it isn't necessary, and it makes it weird for the viewer. Next time, just for kicks, record the video as if you're actually explaining it to somebody, instead of spending an hour or two afterward in post trying to slice and dice it. People don't mind the extra 5 seconds of length of the video if you don't microcut it.

[@FesZElectronics]

Its not 5 seconds of extra material :D This was one of the things that I hated about other videos in the past - it took far more time that it should have, because the creator was just not editing and leaving everything in; in my case that would be far worse since English is not my native language, so I take quite a few brakes in which I just need to think about what the next words are. I will try to do this less, I understand why its not likeable though, thanks for pointing this out.
