Matrix-Reactance Frequency Converter Based on Buck-Boost Topology

This paper deals with a three-phase direct matrix-reactance frequency converter (MRFC) with buck-boost topology and includes a description of its topology and operation plus presentation of the results of an investigation of its properties. Presented too is a conceptual development of the frequency converter based on a buck-boost matrix-reactance chopper (MRC) with source switches arranged as in a matrix converter (MC). The averaged state space method is used in the analysis. In the control circuit, a classical control strategy, attributable to Venturini, is used for the study of the presented conception. The simulation test results are also presented in order to verify the results of the theoretical analysis. Furthermore, simplified description of the experimental setup, which will be used in next investigations is also presented.
