## Abstract

This article examines a space vector-based bus clamping control approach for an induction motor driven by a three-level inverter for use in electric vehicles. The suggested controller incorporates a new region identification methodology by combining a basic v/f control with a bus clamping mechanism. In terms of power quality, torque ripple, and capacitor voltage balancing, a comparison to the usual SVPWM approach is made. Previously, lesser attention is paid to space vector-based PWM using a region selection methodology. This strategy is centered upon some algebraic equations. The surprising thing about this sector is that it is identical to all the others. As a result, computation complexity is reduced. This technique applies to any number of levels. The suggested controller's effectiveness is evaluated using the MATLAB/Simulink environment. Transient and steady-state analyses are used to evaluate the entire system's performance. Additionally, the neutral point balance of the 3L NPC inverter is achieved using appropriate switching sequences.
