Here the DC to AC Inverter which build based MOSFET component IRFP260 as signal amplifier. This inverter will convert DC input 12V, 24V or 48V to become 220V AC power output up to 500 Watts.
This power inverter is a lot more frequency-stable than the 15-minute DC-AC converter and it can be built to operate with battery voltages from 12 Volts to 48 Volts. The basic advantages of this unit are:
All the components, except for the transformer, are mounted on a single-sided printed circuit board. The field-effect power transistors are also fitted to the board, but they are mounted on a heat-sink and provide the support for the board. The board is not to be bolted down to anything.
Pay particular attention to the components, especially the orientation of the transistors and the 10uf electrolytic capacitor. I hate to admit it, but I got a bit of a shock with the first prototype of this board. I made the basic mistake of fitting the electrolytic capacitor the wrong way round. These “little-buggers” DO make a loud noise!
In operation you need to have a fuse in the battery lead. If you intend to load the inverter to 500 Watts, then you will have a current of 45 Amperes at 12 Volts, or only 22 Amperes at 24 Volts. At 48 Volts battery voltage, the current will halve yet again to 10 Amperes.

Hello, the link to the description and explanation doesn't seem to work. Is there anywhere I can find more information on this circuit? Thank you
Did you use a high or low frequency transformer in this project?
yes use a 50Hz mains transformer
