500 Watt Power Inverter 12VDC to 220VAC, skema inverter, skema rangkaian inverter, rangkaian inverter 500 watt, 500 watts inverter circuit diagram,

This power inverter takes 12 VDC and steps it up to 220 VAC. It can be used to run a TV, stereo or other appliance while on the road or camping. In this circuit 4047 is use to generate the square wave of 50 Hz and amplify the current and then amplify the voltage by using the step transformer.

Attention: This Circuit is using high voltage that is lethal. Please take appropriate precautions

How to Calculate Transformer Rating
The basic formula is P=VI and between input output of the transformer we have

Power input = Power output

For example:
If we want a 220W output at 220V then we need 1A at the output.
Then at the input we must have at least 18.3A at 12V because:

12V x 18.33 = 220v x 1

So you have to wind the step up transformer 12v to 220v but input winding must be capable to bear 20A.
