Abstract (EN): Multilevel inverters based on the series connection of H-bridges are the most modular multilevel inverter family. The use of a large number of these devices connected in series, controlled by modulation based on the fundamental frequency, allows to obtain an output voltage of the inverter with low harmonic distortion and low losses in the inverter. This paper analyses the main characteristics of a fundamental frequency modulation method applied to multilevel inverters based on cascaded H-bridges (CHB). Particular emphasis is given to the harmonic distortion of the output voltage and the range of variation of the amplitude of the fundamental component in static and dynamic conditions. It is also discussed the implementation of the algorithm in real-time and in an FPGA platform. Simulation and experimental results are presented with a different number of H-bridges. © 2019, ICST Institute for Computer Sciences, Social Informatics and Telecommunications Engineering.
