Simple powerfull inverter

The scheme of Simple powerfull inverter. To increase the output power is necessary to use dual-field-effect transistors, and, of course, the battery capable of providing the appropriate current. For example, to get at the output of 240 watts, the battery should give over 20 A. If you use a transformer 24, you can use the battery for 24 V and current consumption in this case is slightly more than 10 A.
