The current limit of the traction inverters has been relaxed by using silicon carbide devices. The integrated design of the traction circuit system is required. In this paper, the relationship between the speed-torque characteristics of the railway vehicle and the energy saving effect is presented. We considered a model for calculating the mass of induction motors and inverters. The relationship between the V/f characteristics of induction motors and the reduction size and weight of the traction circuit system are discussed. An integrated design method to maximize the output power density of traction circuit systems for electric railway vehicles is revealed.
