Sažetak
This paper analyzes the possibilities of applying a diode-clamped three-level inverter (NPC - neutral point clamped)in electric traction. This possibility was analyzed by simulating a traction profile of an electric tram. A computer program enabling comparison between different topologies, modulation strategies and control laws was made to conduct the simulation. The model used in the simulation is based on the averaged model of the three-level inverter. The model is averaged within one switching period. Semiconductor losses can be determined using the data from various semiconductor vendors and can be included in the averaged model. Temperature increase of each of the switches in the converter are determined, based on the known thermal model of the semiconductor module. The three-level converter is compared to the two-level one based on the data acquired via simulation. Some possible further investigations are suggested based on the advantages and disadvantages of the three-level topology.
