Modeling, Analysis, and Prototyping of a Cascaded HBridge Multilevel Inverter System Using TI F28379D Microcontroller for High-Voltage Applications

An investigation of the design, evaluation, and testing of a high-voltage-generating multilevel inverter system based on the TI F28379D microcontroller is detailed in this work. To evaluate the proposed system’s performance and feasibility, the research includes developing mathematical models, control algorithms, conducting simulation studies, and validating the results experimentally. We select a cascaded $\mathbf{H}$-bridge architecture for high-voltage generation to leverage the precise control and modulation capabilities of the TI F28379D microcontroller. We applied the CHB-MLI simulation model in MATLAB Simulink. Afterwards, the development of a 1 kVA prototype inverter at IPR confirmed the modeling results. Theoretical studies, simulation results, and experimental results demonstrate the effectiveness and robustness of the designed multilevel inverter system, underscoring its potential for a wide range of industrial applications.
