Active filter for multi-pulse rectifiers with magnetically coupled reactor

Abstract

The article presents the simulation and laboratory tests of multi-pulse rectifiers with magnetically coupled reactors, connected to the power grid and cooperating with an active parallel filter (APF). In the study, two types of multi-pulse AC/DC rectifiers were compared, namely 12- and 24-pulse rectifiers. It presents the operating principle and the results of the simulation and laboratory tests. The considered systems enable the reduction of undesired high harmonics in the power supply grid current. For the manufacture of multi-pulse rectifiers, assemblies of magnetically coupled spring reactors configured in the TDSλ system were used.
