Power frequency sine wave inverter

Overview

Please use the attached PCB for prototyping!
The DC-DC inverter uses 220V AC power; the input voltage should ideally not exceed 36V. The chip's withstand voltage is 40V, and the capacitor's withstand voltage must be greater than the operating voltage.
You will need to drill holes for the heatsink yourself.
I recommend the SKD502 MOSFET; it seems to offer the best value in the TO220 package, mainly because it's easy to drive.
An EMI inductor is connected to the output; you can short it if not needed.
I used a cheap AC meter from Taobao (around 2 RMB), which seems adequate.
The control module uses EG002: https://item.taobao.com/item.htm?spm=a21n57.1.0.0.6081523cXXl1Ul&id=529512690892&ns=1&abbucket=13#detail

LM3 Getting Started
It's been a long time since I got the board, and the beginning is finally over. Now I've started learning lm3s811. At the beginning, I learned how to use the software and the basic hardware resources.
