50 watt 12 VDC to 220 VAC Power Inverter

Image
This is the Simple 50 watt 12 VDC to 220 VAC Power Inverter. Power inverter (UPS Uninterruptible power supply) is a very useful device which can convert Low voltage from a DC source to high voltage AC. The most common power inverter is 12V to 240V inverter. Perhaps that is because 12V batteries are common. This type of power inverter usually draws current from a DC battery. This battery should be able to provide a high flow of electric current. Normally lead acid batteries can server this purpose well. This current is then converted to 240V square wave alternative current so that we may empower those electric appliances which work on 240V instead of 12V. Inverter falls in the category of expensive devices so many people don’t buy them even they need them. What if I tell you how to build an inverter (UPS Uninterruptible power supply) yourself?  Iverter circuit diagram  Parts.
