Abstract

The invention discloses a magnetically integrated 24-pulse rectifier traction power supply system for electric propulsion, which comprises a 24-pulse magnetically integrated rectifier transformer adopting staggered winding arrangement and four three-phase bridge diode rectifiers. The four three-phase output windings of the rectifier transformer are respectively connected with the three-phase inputends of the four bridge diode rectifiers. At the same time, the head ends of the input three-phase windings of the upper and lower bridges of the 24-pulse magnetically integrated rectifier transformer adopting staggered winding arrangement are connected in parallel in turn to be used as the three-phase input end of the magnetically integrated 24-pulse rectifier traction power supply system, and the output ends of the four bridge diode rectifiers run in parallel and provide a stable DC voltage for an electric propulsion system as the DC output end of the magnetically integrated 24-pulse rectifier traction power supply system. The power quality of the network side and the DC side of the rectifier traction power supply system can be improved, the volume and weight of the power supply systemcan be significantly reduced, and the complexity of the connection process can be reduced.
