Build 100W Inverter – Step by Step

This is a step by step how to build the very simple power inverter. An inverter will convert 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. Lets start it…

First, you need these parts to build 100W inverter:

Circuit Part List

Resistors
22K Resistor 3x
220 Ohm Resistor 2x
100 Ohm Resistor 1x

Diode
4007 Diode 1x
10V Zener 1x

IC
4047 IC + 14 Pin IC socket 1x

Capacitor
0.01uf capacitor 1x
100uf capacitor 1x

MOSFETS
IRF 3205 mosfet 2x

Varo Board

Transformer
Center Tap (CT) Transformer. Input 12-0-12, while the output refer to your standard home electricity (every county may different).

In the tutorial, it use 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.

Please take a note that this inverter can handle up to 100w of load but be careful, on the 100w of load you should use Heatsinks with those mosfets.
