very very easy inverter circuit 500va or 500w

Here is a simple but powerful, stable and efficient schematic diagram for a 500w modified sine wave inverter circuit. Originally I used a 555 timer and a decade counter to produce the modified sine wave, but then I thought a simple PIC micro controller with its internal clock would produce a stable 50Hz frequency without the need . As you can see its a very simple circuit.
