Analiza rada elektroničkih energetskih pretvarača u programskom paketu Matlab-SimPowerSystems
, 2015 Energetic transformers have wide usage nowadays and consist of series of electronic elements and energetic electronic frames. They usually include thyristors which perform management in quadrants, so according to the number of thyristors, it is possible to define stage of transformer's complexity, i.e. its mode.
