Switching elements are modelled as resistances with step-wise variable parameters, what allows to describe the converter by a linear infinite set of equations. The analysis in frequency domain is presented on example of the one-periodic control strategy. External systems were also added using the Thevenin method approach. The numerical calculation results of a linear equations set were verified by the variable structure method in a time domain and the numerical convergence was confirmed. Furthermore, the exemplary complex system was analysed using the cascade method and current waveforms were obtained.}, type={Artykuły / Articles}, title={Description of matrix converter in frequency domain}, URL={http://www.journals.pan.pl/Content/84818/PDF/03_paper.pdf}, doi={10.2478/aee-2013-0031}, keywords={harmonic balance method, atrix converter, requency domain}, }
