The invention discloses a converter, permanent magnet traction equipment, a railway vehicle and a power unit assembly, the converter is applied to the railway vehicle, the converter comprises a box body and the power unit assembly, the power unit assembly is installed in the middle of the box body in the length direction, the power unit assembly comprises a radiator, the radiator comprises a plurality of radiating fins, and the radiating fins are arranged in the box body. The plurality of radiating fins are stacked at intervals along the height direction of the box body and extend along the width direction of the box body, so that the power unit assembly is arranged perpendicular to the driving direction of the railway vehicle, the layout of the power unit and the radiator in the box body can be changed, the width and the weight of the whole equipment can be greatly reduced, and the power unit assembly is more convenient to use. The size and the weight of the converter are further reduced, better miniaturization and lightweight design of the converter is realized, and the practicability and the reliability of the converter are improved. According to the technical scheme, the size and weight of the converter are reduced, and the miniaturization and lightweight design of the converter is achieved.
