“…For improved performance, the authors propose the use of multi-level inverters [24][25][26]. The research also uses and compares various control methods [27][28][29][30][31][32], but most solutions focus on the analysis of electromagnetic torque ripples and improving control quality using the DTC method, where ripples of large amplitude are inherently present. These articles focus on minimizing these ripples [33][34][35][36][37][38][39].…”

This article presents a harmonic analysis of the stator currents of a squirrel-cage induction motor fed by a voltage source inverter with PWM space vector control (SVPWM). The influence of PWM switching frequency and dead time (dead band) of controlled transistors on THD and electromagnetic torque ripple is shown. The aim is to determine the lowest switching frequency of the transistors for which the drive will operate correctly. Characteristics were determined as functions in the form of THD (fPWM), where the least square approximation was used for stator current measurements when the PWM switching frequency was changed. The approximations were realized for simulation and experimental results. To clarify the results, the operation of hardware PWM circuits in microcontrollers is analyzed.
