I found this inverter circuit online
I can't read it , can you explain it to me
thanks

 

Looks like the drivers are identical, with top stage phase shifted
by 180 degrees.

Nayter, first tell me what you can recognize. Only a very small portion is relevant as an inverter.

thanks !
does the top stage needs to be shifted ? when I add the same transistor in the same location at the lower half it gives the same output signal

Okay so i can't clearly understand the transistor that inverts the signal ( as i wrote in previous reply ) other than that , the 2 other transistors control the mosfets in each half and the mosfets role is to amplify the current to gain more power is that right ?

 

This circuit is a poor attempt at a power inverter, to begin with. yes, that extra transistor is intended to serve as a phase inverter, but there is still the problem of the two sides not being quite right at exactly 180 degrees out of phase. Each set of 2 FET devices has the gate drive not quite enough for adequate turn on. Then, using a 555 as the driver does not assure an exact 50% duty cycle for the two sides of the inverter. So the circuit is not a good inverter even in theory.

There are a whole lot of good inverter circuits published, but this is not one of them.
