| Abstract |
This paper deals with a three-phase matrix-reactance frequency converter (MRFC). The analysed MRFC topology is based on buck-boost matrix-reactance chopper (MRC) one with source synchronous connected switches (LSCS) set arranged as in the step-up matrix converter (MC). The MRFC in question makes it possible to obtain a load output voltage much greater than the input voltage. Presented in this paper is a description a method for the analysis of the steady and transient state properties of presented MRFC. The static and dynamic characteristics of the presented converter under the control strategy proposed by Venturini are fully analysed on the basis of the circuit model development by the DQ0 transformation. Various static converter characteristics such as voltage and current gain, input power factor are completely analysed. Transition characteristics are also analysed by a small-signal model. The usefulness of the models is verified through computer simulations with good agreements. |
