Traction transformer is the core component of EMU traction system. It can convert high-voltage electric energy obtained from the catenary into suitable voltage level for the input of traction container. Due to abundant high order harmonics produced by the four-quadrant rectifier of the traction container, secondary windings of the traction transformer generate ferromagnetic noise which is uncomfortable to human ears. Guaranteeing traction performance and minimizing the ferromagnetic noise by traction transformer at the same time is a difficult task in EMU design. In this paper, operation principle of four-quadrant rectifier and traction transformer ferromagnetic noise generation mechanism are studied through modeling and simulation in Matlab. Noise design and suppression of EMU traction transformer are described, which provide the references and ideas for subsequent project.
