Electric Solar Converter

[electrolives]

I want to understand what is the reason for this circuit and each part of it? Can you explain this?

I don't know where you got that example from but it is totally unworkable and not worth spending any time upon!
More practicable and working examples can be found on several silicon manufacturers websites such as ST, Microchip etc

Well it's not a 'circuit', more a crude block diagram to suggest a way of doing it.

With out commenting on "the circuit"; The question is "reason why?". "Explain".

The point of the circuit is to take DC and make AC.
Solar power is DC. Direct Current. Like a car battery.
"Grid" power, like from a wall out let is AC. Alternating Current. It switches + and -, 60 or 50 time a second.
The parts "MOS1....MOS4" are like switches. Then can be on or off.
The point of the circuit is to take DC and make AC.
For a short time MOS1 and MOS4 are on while 2 & 3 are off. This connects the (+) side of the power (see red lines).
For a different short time MOS2 & MOS3 are on and connect (-) to the power line (see blue lines).

Another way to say it. Put the battery across the power line for a short time, remove the battery, turn it arround, put it back across the power line. (DC is switched around to make AC)

I hope this helps. Very simple answer. It is a little more complicated that the simple answer.
Please ask more questions.

Thank you so much for your help!

Note that it is the "Controller" that determines the frequency and firing of the gate voltages. If trying to sync to the actual power line, the controller would also be measuring the grid frequency and phase to make sure it feeds power to the grid in sync with the mains.

I think this is the appreciable way to make us understand why circuit happens. Thanks for sharing this your ideas with an informative illustration
