Simulation of multilevel converters
Strieš, Jakub ; Huták, Petr (oponent) ; Lažek, Tomáš (vedoucí práce)
This bachelor thesis deals with the search of multilevel voltage converters. The aim of the work is to acquaint the reader with the basic topologies in the first part and to simulate selected events on some of them in the second part. Topologies with clamping diodes, floating capacitors, cascaded H-bridges and modular MMC converters are presented. The simulations are performed for the last two mentioned topologies. The PWM methods used in this topic are also described. The results of individual simulations are presented in the final part in the form of graphs. Together, four events were simulated, namely direct connection to the network, start-up by ramp, failure of one phase and disconnection of the load. A block simulating an asynchronous motor was used as a load for the models.
