great job !
Thanks :+1:
Thanks for another great write-up
Great writeup!! Really appreciate the time & effort you put into this.
You’re a wealth of information, many thanks!
You have my appreciation for the fine work you do in explaining how electromagnetic current can be modified in what might seem ‘magical’.
As J B S Haldane has been reported to have said, “Things are not stranger than you imagine, they are stranger than you can imagine”.
I am really impressed. :+1:
WOW!!!
Excellent. Thank you.

I’m eager to find the time to read this.
Thanks HKJ!
That was a great read :+1:
Very detailed article! Thanks!
Excellent article! I have no knowledge of electrical engineering, but I was still able to understand this article.
Is capacitor failure the most typical reason these chargers (and other consumer electronics) eventually expire?
I am happy to hear that.
Probably and when the capacitor fail it might kill other parts in the process.
If you look on you-tube for tv/monitor repairs, you will see that many of them starts by replacing capacitors.
Cheap capacitors placed at a hot location is a short-lived deal. On large multi port charges this will seldom be a problem, the number of hours that type of charger is hot is very low.
Hmm.
Have you ever heard about capacitor power supply (that are without transformer)?
95% of modern devices are equipped with them. And I think 99% of problems arise from them.
I would not call a capacitive dropper a real power supply.
They do not isolate from mains, i.e. everything is still mains connected and need the full isolation.
They have a very bad power factor.
But they are useful for small closed mains powered devices.
Thank you for this explanation. I’ll bookmark it. We have come a long way since the 4 diodes in a bridge plus capacitor.
And that was already radio-2.0 for me. Because my first kit radio had a triode… on batteries! What a disappointment. Many years later I found out that my father believed he had found a trusted source of almost-good-as-new zinc-catbon batteries.
uh…wow this is amazing.
