Another topology for the multilevel converter is available for the high speed train in this paper. Three-phase induction engines are driven by voltage source inverters. This chapter investigates different multilevel converters. The speed and contortion which exists in three-phase locomotives was controlled by variable voltage, variable frequency (VVVF), and the modulation index was expanded to reduce the distortion in the yield voltage and current. In this chapter the modulation index was increased with respect to the frequency of the three-phase induction motor. In current insulated gate bipolar transistor (IGBT) trains voltage stresses exist. These are investigated and reduced using a proposed framework for WAP-7D locomotives. Simulations were done across an entire district investigating speed, torque, voltage, and braking effort in traction motors, utilizing MATLAB programming.
