Abstract

The voltage fed inverter with LCL resonant load has been considered. The paper presents the load topology changes phenomenon, which leads in VSI-LCL converter properties alteration. The phenomenon has been investigated and the causes of variability are described. The chosen parameters of LCL variable topology circuit are analytically defined. The range values of new parameters are determined and illustrated. The new variable frequency converter concept, based on topology variability phenomenon is presented and discussed. The numerical calculations results and the laboratory tests are shown.
