The invention relates to the technical field of traction auxiliary converters, in particular to a new energy hybrid power shunting locomotive traction auxiliary converter based on a closed scene, and solves the technical problems that an existing internal combustion shunting locomotive traction converter applied to the closed scene is high in fuel consumption and large in noise. The system comprises an uncontrolled rectification circuit module, a traction DC/DC circuit module, an intermediate DC loop unit, a traction inversion and chopper circuit module and an auxiliary power supply module. The system has the characteristics of high efficiency, low noise and the like, is an important measure for implementing digital, intelligent and green development, provides a feasible technical scheme for intelligent transportation in a closed scene in the metallurgical industry and digital transformation and intelligent upgrading of iron and steel enterprises, realizes high integration of functions of traction, excitation, DC/DC, assistance, a charger and the like, and has a wide application prospect. Higher efficiency, lower loss and less emission are realized, a green, efficient and intelligent system product is created, and the old internal combustion shunting locomotive is assisted to be transformed, updated and upgraded.
