From the project
Matlab, Simulink, Hardware and C-code for a custom inverter project.
A low-voltage three-phase voltage source inverter designed from scratch to drive a BLDC/PMSM gimbal motor. The repo covers the whole path from motor model to spinning shaft: Simulink models, LTspice circuit simulation, KiCad PCB designs (three revisions), and STM32 firmware that generates sine-weighted PWM (SPWM) with the timer and DMA hardware instead of CPU interrupts.
