Here is the circuit diagram and explanation for transformerless power supply.

Circuit diagram for 6v power supply. For transformer use 230v or 110v to 9v or 12v output transformer. Transistor variable power supply 1a 0 30v. It will keep a stable voltage when it has any load. 7806 employs internal current limiting thermal shut down and safe operating area protection making it essentially indestructible.

What is a variable power supply. The output current of the circuit is upto 1a. Use any 2a diode bridge or. Dual 6v power supply circuit using lm317lm337.

Lm7806 is a voltage regulator ic of lm78xx series which is a series of fixed output voltage regulator ics. Simply said it is a power supply that can adjust the output voltage or current. To protect the circuit transformer rectifier capacitor filter an led indicator and the regulator ic. Circuit diagram of 5v dc power supply below is the circuit diagram for the said project.

We can convert the high voltage ac into low voltage such as 5v 6v 9v 12v dc without using the transformer which is called transformerless power supply. Voltage and frequency can depend on your country fuse. 12v dc power supply schematics. But it still has the same characteristics as a fixed regulated power supply.

Here is the variable dual lab power supply circuityou can select voltage levels are 3v5v6v9v1215v at 1a and 3v 5v 6v 9v 12v 15v at 1a use ic lm317 for positive volt and lm337 for negative volt controls voltage output by s2 for vout and s3 for voutthe transformer is 2a size. First power supply circuit is built with bd139 one zener diode and a few passive components. Here is the circuit of a 6v power supply using lm7806 ic. Adjustable power supply power supply variable power supply 3v to 9v dc converter this is the circuit diagram of 3v to 9v dc converter which capable to deliver output voltage about 104v on no load and 96v at30ma.

You get the main supply. Each of the schematic is very simple to construct and will function without problems if you respect the maximum power supply ratings. 12v bd139 power supply circuit. Huge heat sink is required in this circuit as 2n3055 transistors produce large amount of heat at full load.

6 volt regulator using ic 7806 description. Here is the elementary 6v 1a power supply circuit using 7806 ic. Adjustable power supply circuit. The 7806 three terminal positive voltage regulator is available in the to 220d pak package making them useful in a wide range of applications.
