Abstract:
In this project, quasi network based sparse matrix converter and a compensation method based on a fuzzy logic controller to compensate the input voltage. The structure of an SMC to reduce the number of unipolar power semiconductor switches employs a quasi network to overcome the inherent limitation of the low voltage transfer ratio of conventional matrix converters. Although the SMC is a two-stage converter, it directly connects between a source and a load through a quasi network, which is designed to have smaller passive components as the only purpose is voltage boosting. The operational principle of the SMC is described and its modulation strategy is explained. Simulation results are shown to verify the feasibility of the SMC and its operation.
