300W pure sine wave inverter circuit diagram based on STM32, control software

Filter 18.432M

Overview:
I am a pure rookie, because of the interest in the inverter, after consulting various types of information, pondering for four or five months, after two revisions, made this pure sine wave inverter. The design power is at 300W. From DC boost to SPWM to generate sine waves, both use stm32c8t6 as the main control chip, and provide high voltage, low voltage, over power, and short circuit protection. Now open source. I hope to communicate with friends who like to do inverters and improve together.
The SPWM voltage regulation method temporarily adopts the 310/DC modulation ratio method.
