Abstract
The paper deals with analysis and modelling of a new type of single-phase supplied AC/AC converter with two phase outputs. It consists of single-leg half-bridge matrix converter loaded by resistive-inductive load in series connection. There are two problems solved in the paper: a) creating of second output phase shifted by 90 degrees against original one, and b) providing of frequency control of both orthogonal phase systems able supplying a two-phase electrical machine. As simulation results are given: harmonic analysis of the voltage of both phases; maximal possible reachable current waveform under R-L load with parametric changes of the time constant of the load. The simulation is resulting to recommendation for fair and right design of the converter, and demands to single- or two phase input supply voltage, respectively, under passive R-L or motoric load.
