Pcb Layout 12v Power Supply Circuit Diagram

Though very cheap and easy to build these types of power supply circuits cannot support heavy current and are normally limited to 200 ma or so.

Pcb layout 12v power supply circuit diagram.

Two concepts of the above transformer less type of power supply circuits are discussed in the following couple of posts. The most commonly used of type of power supply circuit is the smps switching mode power supply you can easily find this type of circuits in your 12v adapter or mobile laptop charger. Each of the schematic is very simple to construct and will function without problems if you respect the maximum power supply ratings. First power supply circuit is built with bd139 one zener diode and a few passive components.

In this tutorial we will learn how to build a 12v smps circuit that would convert ac mains power to 12v dc with a maximum current rating of 1 25a. 1 5v 3v adapter usb to 1 5v or 3v converter circuit small uninterruptible ups. By using high voltage capacitors. This kind of dc power supplies uses a pcb so you can use two case types for ic1 to 220 or to 3.

The regulation of this 12 volt power supply is made with tr1 multiturn. Ic1 must be placed on proper heatsink. This ac to dc power supply can output 5a in continous operation and 12a peak current. 1 5v 3v 4 5v 6v 9v at 1 5a selector voltage regulator.

The transformer is one of the main components in a power supply circuit because we need to convert the higher voltage available in the power point into a lower voltage we needed.
