The three-level neutral-point clamped inverter represents a significant advancement in direct torque-control systems for asynchronous motors. A significant achievement of this study lies in the comprehensive analysis of a random frequency-modulation algorithm, which demonstrates its efficacy in substantially reducing the amplitude of harmonic oscillations and minimizing switching losses. This simplifies filter design and minimizes thermal dissipation in power transistors, thereby enhancing the overall reliability and efficiency of the system. Additionally, the implementation of a six-position torque regulator with a fixed sensitivity zone, applied in direct torque control based on the three-level inverter, improves the stability of the stator flux linkage and reduces the switching frequency of transistors. Numerical simulations conducted in the Matlab/Simulink environment indicate that the proposed algorithm reduces switching losses by 15% during transient states and by 2% during steady-state operation while increasing the system’s efficiency by 2% compared to conventional methods. These findings highlight the potential of the proposed solutions for application in energy-efficient drive systems.
