The article presents the principle of operation, design method, and results of laboratory and simulation tests of a 24-pulse power network converter system with direct-voltage output, the concept and practical realisation of which was worked out within the framework of a research project financed by the State Committee for Scientific Research. The presented converter allows significant reduction of undesirable higher harmonics in the power network current, including the elimination of harmonics of an order 23 and 25. The 24-pulse nature of operation of the system is obtained using three sets of coupled three-phase power network reactors (CTR).
