Introduction: 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
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
