Abstract: This master’s thesis is about researching different modulation strategies used on one-phase inverters. Given results and quality of the particular modulation strategy will be measured on output terminals of the whole system or load, which will be, for this purpose, a classical pure resistive load. Signal response will be measured with oscilloscope and the obtained signal will be saved in CSV form for further computer analysis using MATLAB/Simulink. Stored results will be passed through Fast Fourier Transformation method, which can estimate the magnitude of higher harmonics component in the output signal and thus quality of the signal. Whole algorithm and low-level signal generation is performed with TMS320F28335 microcontroller which supports MATLAB/Simulink to be compiled in C language. Real »Power board« is done with the milling machine with prior designing in Altium Designer PCB software package.Keywords: one-phase inverter, different modulation strategies, TMS320F28335, power board, simulationsPublished in DKUM: 22.11.2019; Views: 656; Downloads: 98 Full text (3,96 MB)
