Intro: DC to DC Buck Converter DIY || How to Step Down DC Voltage Easily

A buck converter (step-down converter) is a DC-to-DC power converter which steps down voltage (while stepping up current) from its input (supply) to its output (load). It is a class of switched-mode power supply (SMPS) typically containing at least two semiconductors (a diode and a transistor, although modern buck converters frequently replace the diode with a second transistor used for synchronous rectification) and at least one energy storage element, a capacitor, inductor, or the two in combination. To reduce voltage ripple, filters made of capacitors (sometimes in combination with inductors) are normally added to such a converter's output (load-side filter) and input (supply-side filter).

Step 2: Where to Buy & Making Part ( PCBWay ) :

Hey!

Where to get the PCBs for your Project ?
Currently there are many companies that are dedicated to manufacture printed circuits, but not all can get small runs at a good price. Luckily, we now have Internet and it is much easier than before. We can look for companies anywhere in the world, and it is easier to find a manufacturer that makes our prototypes (PCB) at a good price. One of the largest companies in the sector is PCBWay , and this company PCBWay is a manufacturer of printed circuits in China. You can order your designs - Low Cost PCBs .

You can design Gerber files for this circuit and upload it on their site ( www.pcbway.com ) .

Shipping of assembly orders take only 3 to 5 days also, they are the best in PCB manufacturing area :D

Anyways, here as you can see i have given only 3 turns to the secondry of the transformer for reducing the voltage.

Step 3: Testing Time :

After you have connected the circuit to the transformer exactly as shown in the picture above, it should start producing low voltage and high current.Changing the number of turns in the secondary will decide the O/P voltage and thickness of the wire will decide the output current.

Don't Forget to check out the video for step by step understanding.

Thankyou !!!!!
