Yup, I have seen the one about diodes before. Never seen the other one. After watching both I have a better understanding than before. Thanks!
In the pictures of my power supply, there is no linear voltage regulator or trim pot. Does that means that the voltage is regulated by the diodes? I know that it is a unregulated power supply, but how did the manufacturer drop the voltage to 9.5v 1.5a. I understand the transformer drops the voltage, but after adding resistors, caps and a bridge rectifier, is it going to be the same voltage or amps as what comes out of the transformer? I know that the electricity comes out of the transformer in AC. Once it goes through the diodes/bridge rectifier, the electricity comes out in DC. Does the transformation effect the potency of the electricity in voltage or amps? That is what I do not get. Also, can I safely use specific diodes or resistors to get the appropriate voltage amps I need?
In the second video, the guy puts on a pot at the end to dial in the voltage. I thought that was pretty cool but I would not like to add new components to the original design. I would prefer to swap the diodes, resistors, cap and keep the PCB and transformer.
I am looking at buying a BK Precision 2712 DMM for doing all of my testing, current and future projects.
Thanks for the videos. They are very informative. I am very excited about getting the new DMM to be able to run test.
Sorry, I'm a bit of a noob, but I'm at least willing to learn. If you know of any good forums books or anything on the subject, I'd gladly appreciate any leads. Thanks!
