Transformerless Power Supply (220V AC to 14V DC) circuit + pcb

I am pretty new to SMPS circuits. I understand there's a bleeder resistor, a flyback diode circuit to power the transistorized osc circuit. I guess that the current around the MOSFET will be like a...

Learn how to design Linear DC Power Supplies to convert AC voltage into positive or negative regulated DC voltage. We'll see how linear supplies differ from switching supplies, we'll learn how to use voltage regulators, and we will build a nice power supply for our workshop.

DIY Lab Bench Power Supply [Build + Tests]: In this instructable / video I will show you how you can make your own variable lab bench power supply which can deliver 30V 6A 180W (10A MAX under the power limit). Minimal current limit 250-300mA.Also you will see accuracy, load, protection and ot…

This is the LED light power supply for a 5-watt LED light. this circuit can make 5 watts. here 4 diodes to make AC to DC voltage

Computer Power Supply to Bench Power Supply Adapter: There are a lot of ways that you can re-purpose and reuse old electronics. For instance, a computer power supply can make a great bench power supply for your workshop. There are already a lot of tutorials online that show how to convert an old co…

One of the more popular projects for beginners in electronics is a power supply. Yes, you can always go to Amazon and buy a nice power supply, but unfortunately, we haven't set up our Amazon affiliate...
