Make 350W Power Inverter 12V 220V From OLD Computer Power Supply

Hi Guy today we make Make 350W Power Inverter 12V 220V From OLD Computer Power Supply

Step 1: Step 1: Watch This Video

This video show you how to make 350W inverter from old computer power supply.

Step 2: Step 2: Make the Schematic

In this schematic i use Sg3525 and 2 mosfet IRF3205 with transformer from old PC power supply.

The max power can reach 350W.

I use Eagle software for make Schematic.

Step 3: Make PCB by Upload Gerber File to the JLCPCB.COM

Go to JLCPCB.COM for make PCB online

Only 2$ /10pcs for 2 layer PCB and Big Discount on First order Shippinghttps://jlcpcb.com/

Upload your gerber files and fill in Shipping Adress then click PAY.

Step 4: Received Your PCB After 2 Day

The PCB look great and so beauty

Step 5: Order the Component

List of part here:

You can buy it from any electrical store.

1 x heat sink

2 x IRF3205

4x 150Kilo ohm resistor

1 x 47 ohm resistor

3 x 10kilo ohm resistor

2 x 100 ohm resistor

3 x 20kilo ohm resistor

4 x FR307 Diode

1 ATX transformer (from old computer power supply)

1 x resistor 330kilo ohm

3 x 104 capacitor.

1 x 102 capacitor.

1 x 100uf/16v capacitor

1 x 1000Uf/16v capacitor

1 x 220uF/400v capacitor

1 x IC KA3525 (Sg3525)

1x Inductor( from PC power supply

Step 6: Solder PCB

Solder all component to PCB. We have the name on the top PCB. So this very easy

Step 7: Check Again.

Check all component were correct.

Step 8: Finish and Test

1: Connect the output with Load.

2: Connect input with battery. I use 12V battery

Be Careful with high voltage, electric shock will kill you do not touch any output component
