12v ct 12v 2a transformer d1 d2.
Simple 12v power supply circuit diagram.
The final project i wanted to build was a wall adapter with a usb socket to charge my iphone.
Make 12v dc power supply.
1 2k 0 5w resistors led1.
5v power supplies digital power supplies.
Each of the schematic is very simple to construct and will function without problems if you respect the maximum power supply ratings.
Simple dc regulators 12v 15v 30v.
This circuit can be very useful on the places where you want high current like 3a.
A lot of 6v supply diagrams.
Here is a very simple and useful project of a 12v power supply circuit using lm7812 ic.
This is a schematic of a simple dc 12v 3a power supply circuit using 2n3055 transistor.
Here are 4 simple 12v power supply circuits with output voltages around 12v.
2 200uf 25v electrolytic capacitor r1.
I have built many circuits in my life but this is actually the first time i ve built a power supply circuit from scratch.
1 5v 3v adapter usb to 1 5v or 3v converter circuit small uninterruptible ups.
1n5402 3a diode c1.
Parts you will needs.
Fuse 1a copper wires and nail 0 5inch ac line power.
It has many built in features like thermal shutdown short circuit protection safe operating area protection etc.
But first i wanted to start by creating a simple circuit that converts from the main power voltage 220v or 110v to 5v.
Figure 1 the simple 12v 2a power supply circuit diagram.
Leds as you like s1.
It is very difficult to find that type of regulated ics which deliver that high current so this circuit will work on the places where.
