PDFAbstract: This work shows the design and implementation of a cascaded single-phase modular multi-level inverter with asymmetric topology. The output of the inverter can be adjusted to 7, 15 and 31 voltage levels using a step modulation. The selective harmonic elimination (SHE) technique is used to determine the switching angles of the mosfet. The results were simulated in MATLAB and verified by the implementation of the inverter, evaluating its performance using the total harmonic distortion (THD).
Keywords: Multilevel inverter, SHE, step modulation, THD, MATLAB
