Understanding Power Supplies, Generators, AC and DC.

http://tvrepairinfo.com
In this video I demonstrate some of the principles behind power supplies, AC and DC Generators, transformers, switch mode power supplies, linear power supplies and AC to DC conversion using Diodes and Bridge rectifiers.
Power supply repair make up a large portion of the repairs I do and they are fairly easy to troubleshoot. In case your interested in learning more about switching power supplies check out this link. http://www.tvrepairinfo.com/switch-mode-power-supplies.html

Hi Mike -

Greetings from NJ. You have done a great job explaining the principles behind switching power supplies. Kudos to you. Just a bit of correction: it's 'sine' wave, not 'sign'. In any case, I'll continue to be a loyal subscriber. Never been to Oregon but judging from your other videos, it must be awesome! Let me know if you're ever in NJ! - Nelson

@nlimchua Nelson Thanks for pointing that out. God bless.

@GrantsPassTVRepairs Dave, I've also been playing around with crystal resonance testing. Normally, a dipmeter would work great by itself or with a scope; I also found that you could use a function generator's center wire (with a small ext. wire as antenna) to tickle the resonance of the crystal and view the peak on the scope. Thought I'd share that.

All the best,

Nelson

PS> errata on my earlier comment, I meant 'Dave'! (sorry)

@nlimchua I also have a dip meter but I never used it to test crystals. Thanks for the info.

I am thinking seriously about training as an electrician. I have no previous knowledge in this area and so I am a little wary. However I found this video very well presented. Many thanks uploader

I too enjoy your ability to explain somewhat complex configurations in a down to earth simple way. Love the visual aids

Brilliant in it's clarity and simplicity. Your vid put the cap on my understanding of the principles of the subject. Your visual aids could not have been better imo. Thank you teacher: you just got another subscribee :-]
