Three-phase inverter system

Introduction: The system uses STM32 as the main control chip to generate three-phase SPWM waves and amplify the power through the half-bridge drive circuit. After filtering, it generates three-phase power. Then it collects the output voltage after the front-end attenuation through STM32 and sends it to the computer via Bluetooth. The host computer receives the data and conducts harmonic analysis using MATLAB.
