Description
Summary:In this paper, a three-phase multilevel current source converter with reduced component count (switches and inductors) is proposed. Multilevel topologies are used in order to increase the power capability of the converter by sharing the power trough n converters. The multilevel topologies also allow to use smaller AC filters or smaller switching frequency. The conventional multilevel current source converter connects n three-phase three-level converters to achieve the multilevel topology. However, the number of switches largely increase as the number of levels increases, as do the number of vectors/complexity of the converter. Even though the topology is presented as a five-level converter, it can operate as a seven-, nine-level, etc. converter. Simulation and experimental results are presented in order to validate the proposed topology and the space vector modulation.
