<b>Half-Bridge VSI Control – ATmega2560 + CHIL</b>

This item contains all files related to the development and validation of a Control Unit for a half-bridge Voltage Source Inverter (VSI), based on the ATmega2560 microcontroller and bipolar SPWM control.The project demonstrates a low-cost, educationally oriented solution for inverter control, verified using Controller Hardware-in-the-Loop (CHIL) methodology with the Typhoon HIL 402 platform.Included in this dataset:MATLAB/Simulink model of the half-bridge VSITyphoon HIL model for CHIL simulationArduino-compatible source code for the ATmega2560 (SPWM implementation)MATLAB scripts for generating PWM pulse tablesRaw oscilloscope measurements and harmonic analysis dataSTL files for a 3D-printable enclosureBasic documentation and wiring schematicsThis work is intended for researchers, educators, and students in power electronics and embedded systems, and supports reproducibility and further development.
