Reactive Power Compensation Device Based on Matrix Converter

Main Article Content

T. P. Sieńko, J. W. Szczepanik


This paper presents an innovative device for reactive power compensation based on direct energy conversion (matrix converter – MC). The entire device consists of a transformer, a multiphase converter and a polygon-connected capacitive load. The authors have developed a converter control method, which enables the transfer and manipulation of the nature of reactive power flowing through the MC. The reactive power output is controlled by adjusting the capacitors’ operating frequency, and its nature is controlled by changing the converter control sequence. The device enables the output’s quick and stepless (continuous) adjustment. Its arrangement eliminates the risk of network resonances which may occurring during reactive flow changes.
