Abstract

The low-voltage distribution system is influenced by ever-increasing harmonics caused by nonlinear loads. A simple and reliable 24-pulse rectifier transformer for high-current and low-voltage is proposed in this paper. The proposed 24-pulse rectifier transformer consists of four secondary windings in which an original delta-extended connection is adopted. First, the existing 24-pulse rectifier system is analyzed. Second, the topology, the phase-shifting principle, the input current and the output voltage of 24-pulse transformer are described. Finally, the simulation results validate the theoretical analysis and the advantages of the new 24-pulse rectifier transformer in multi-pulse rectifier areas.
