Im design a simple inverter, but dont know it function, the value was simple put and choose from other circuit. please give some advice!
1) How you think about this circuit? Izit too simple?
2) If i want to run a household equipment, like fan and light, izit ok?
3) I need to simulate the circuit but this circuit contain PIC controller, how can i simulate it ? Using other component instead it for simulation part?
4) This inverter will give a pure sine wave output 240Vac voltage?
5)If anywrong, please help me to modify it.

thanks......

It has a small chance of working, in the sense of providing AC power. Sine wave output, not too likely, those FETs will have to be powered in the digitial mode. Are you thinking PWM and generating a sine wave that way? There is a reason sine wave invertors cost more, they are more complex and much less efficient, as has been mentioned on your other threads. For simple household equipment like lights and fans, this is not important.

Invertors are a bit more complex than people give them credit for, I think.

Like I said on another website where the same question was posted 3 times:
The transformer is connected wrong so the Mosfets do nothing.
The turns ratio of the transformer is also wrong.
