Unregulated dc power supply. 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. It includes 2 main parts. Simple dc regulators 12v 15v 30v.

This is a schematic of a simple dc 12v 3a power supply circuit using 2n3055 transistor. This circuit can be very useful on the places where you want high current like 3a. This is a type of series voltage regulator. Digital dc regulator if you are looking for 5v dc power supply for the digital.

The figure below shows a project of simple automatic 12v battery backup power supply circuit. Figure 1 the simple 12v 2a power supply circuit diagram. This regulated power supply included a transformer t1 a bridge d1 d4 and the 38v dc filtering voltage regulator circuits which consists of c1 c2 r1 r2 r3 q1 and q2. Leds as you like s1.

Here is a very simple and useful project of a 12v power supply circuit using lm7812 ic. First power supply circuit is built with bd139 one zener diode and a few passive components. The filtered 12 volts dc output is generated the simple transformer based power supply circuit output is 12 volts fixed dc the output is not variable it is fixed 12 volts dc voltages these dc voltages can be utilized in any dc operated 12 volts project like running a 12 volts motor any circuitry that need 12 volts dc a dc fan charger etc this can be used as dc adapter a 12v dc adapter circuit. In many of the circuit applications especially the ones using op amps a dual power supply becomes mandatory for enabling the and ground supplies to the circuit.

First of all we see on the 24 volts regulated power supply circuit diagram. 1 2k 0 5w resistors led1. Each of the schematic is very simple to construct and will function without problems if you respect the maximum power supply ratings. Lm7812 is a three terminal fixed voltage regulator ic comes in to220 package.
