ABSTRACT

A new topology for a two-quadrant converter is presented. In the AC/DC transfer mode the converter works as a rectifier with near sinusoidal input currents (RNSIC), while in the DC/AC transfer mode it works as a square – wave pulse switching inverter. Some suggestions for the converter is characterized by smaller power losses, reduced EMI problems and higher reliability.This new converter topology could have numerous applications. For example, in adjustable speed drives with regenerative braking, wind energy conversion systems and small hydro interconnections with induction generators.
