Hello guys, I'm working on pure sine wave inverter, and for now I made step-up transformer, but I'm not very sure how to make  H-bridge circuit using 4 N-channel MOSFETS for SPWM side, I will use arduino uno for start and after some tests will use attiny85 or other similar microcontroller. The target voltage is 220V 50Hz. I found code for arduino for SPWM. Can someone help me with this H-bridge circuit.

    Is this diagram true pure sing wave do you check the signal wave use to an oscilloscope

    This schematic diagram is not pure sine wave this is just simple boost converter On the end it is 310V DC to get pure sine wave it needs to be driven through Hbridge circuit But im not quite sure how to make it
