100W Inverter Circuit

Introduction: 100W Inverter Circuit


An inverter converts the DC voltage to an AC voltage. In most cases, the
input DC voltage is usually lower than the output voltage of the inverter while the output AC is equal to the grid supply voltage 120 volts, or 240 Volts.

Let's make a fully functional inverter circuit.

Step 1: Inverter Basics | Watch the Video Bellow

This video is only for understanding inverter's concept.

Step 2: Let's Make a Inverter (Watch the Video)

Step 3: Parts List

4047 IC

14 Pin IC socket

3 *22K Resistor

2 *220 Ohm Resistor

100 Ohm Resistor

0.01uf capacitor

2 *IRF 3205 mosfet

100uf cap

10V Zener

4007 Diode

Varo Board

Step 4: Circuit Diagram

Step 5: Some Pictures After Soldering

Step 6: Transformer Information

I am using 12-6-0-6-12 5 amp Transformer you can call it 120 VA transformer. You can use any kind of 12 -0-12 transformer.

Step 7: Now the Inverter Is Ready to Use

This inverter can handle up to 100w of load but be careful, on the 100w of load you should use Heatsinks with those mosfets.

    Question 6 weeks ago

    Please, I need video and pdf instruction on how to make 1000w inverter. Thanks a lot.


    Question 1 year ago on Step 7

    Here the load we use 4 nos 12watts led lamps??? i. e 12w*4=48watts...... We use 48w load using this circuit.
