20 kW 18-pulse diode converter - results of laboratory tests

Abstract

The article presents the principle of operation of a coupled three-phase reactor (CTRλ) used applied in 18-pulse diode converter. Using sets of coupled three-phase power network reactors, the presented converter makes it possible to considerably reduce, at low cost, undesired higher harmonics in the power network current. Selected results of laboratory tests done on a 20kVA 18-pulse diode converter are included.
