great video , I love these educational type videos, EEVblog used to make more of these and I learned a lot of electronics from those! don't mind how many of these you publish a day as presumably like me many people will watch them days weeks or even years later ! subscribed !
Thank you for this video, Eddie. I really like your way of explaining technology. Can you please explain how to choose a NTC thermistor, and explain why every linear power supply doesn't use them...and, more importantly, how to avoid them catching fire?
VG and if f I may add please (not a criticism) just a small point perhaps that a very brief summary using bullet points on a board at the end would highlight to us viewers eg. cap values, types etc including for the parasitics' you mentioned. Using a scope showing the results of your design choices would be nice :+) or even a follow up video? Good work!.
I believe most other channels don't usually publish more than one video a day due to the algorithm, you're gonna have to research/test what works for you.
No I'd rather have them videos on the same day not staggered. What about putting a bleed resistor like 10 megaohms across the capacitor does this help with filtration as well. I mean if the filter cap is not fully charged but in a state of equilibrium does the resistor do this? does this make the cap look bigger in it's capacitance to the circuit. And what bearing on ripple would this add
Thanks John! I will have a bleed resistor. In a previous video on this power supply I take about how to derrate resistors because they used too small a value that actually over heated. I think because it was meant for a lower voltage. The value leaks off too small an amount of current that it will not really affect the ripple. Although it could keep the caps from peak charging too high maybe.
The full statement did not arrive. I met a hyper genius who had a 360 degree scar on his wrist from his watch and motorcycle battery. I love your blast shield but, the conductive bracelet scares me. You do a better job separating circuit parts than I do. I can’t claim that my nerves can justify my phobias!
OK - now I'm with you;) You are correct. I am pretty good at setting things up before I power. But when I do probe around - I will take off my bracelet (most of the time;).
When I think I have a fake capacitor, I order what I know is a real one from Digikey or Mouser then do a visual side by side comparison on construction and labeling, Then throw it on my DE-5000 LCR meter And do a side-by-side test comparison of all the values to determine if it’s real or fake. They have some real good fakes out there.
Good information on reading data sheets and how to use that information...appreciate it!
Thank you!

Thanks Ben - I appreciate you! I’ll keep them coming. I like Dave’s old videos:)
Nice video! Greetings from Argentina!
Thank you! Nice to hear from Argentina;)
Hi Eddie, thanks for the awesome information. Great video.
Any time! Thanks for your support!
video was great thanks for sharing your insights and advice!
Glad you enjoyed it! Thanks for your feedback!

Thank you! Yes that is a great lead up to the next video in this series;)
Great video. Thank you for sharing..
Thank you! I appreciate you!
Is bulk capacitor needed for LLC resonant converter?
Great question! Yes the bulk is needed. An active PFC is recommended to be the first stage.
Great video. Can you show the measurements with and without the series resistor you mentioned?
That’s a great idea! Thank you!
Appreciate your videos!
Thank you!
love the chanell. I am a car audio guy. can you talk avout large capasitors, like Maxwell 3000 Fr and their rolein car audio system
Thanks for the great idea!!

Thanks Genghisnico13! I'll stager it a day to be sure;)

You are the man 👊.
Thanks so much!
well done
Thank you!
My deyar is kishi good thanks from india
Thanks and great to hear from my friend in India;)
but is the theory - Capacitance multiplier - valid?
Thanks for the question. Are you referring to using a capacitor with a regulator?
th-cam.com/video/ifiY1v7wBWo/w-d-xo.html@@KissAnalog
@@KissAnalog I can't relate to that - others call it Remove Ripple
I like plastic watches etc..
Thanks - but not understanding what this means?

Thanks t lech! That is a great idea and a great way to build confidence.
