Resumen

Industrial motor drives, particularly three phase induction motor drives, have been adopting Modular Multilevel Converters (MMC). MMC is utilized in the design of power and control circuits to give the appropriate switching sequences that yield the corresponding output voltage levels. This paper describes the Alternate Phase opposition Disposition Pulse Width Modulation (APOD-PWM) method and fuzzy logic controller used to regulate the 5-level MMC topology of an induction motor. The MMC's switching mechanism is essential for enhancing the induction motor drive's power quality. The converter can be used as a source of controlled voltage because it has numerous distinct voltage levels accessible. Researchers have improved the application of fuzzy logic for Direct Torque Control (DTC) in variable speed drives that rely on multilevel inverters in the past few years. The MATLAB/SIMULINK simulator is the foundation of our suggested method, which measures the effectiveness of direct torque control with respect to ripple in current, speed, torque, and transient response. Both the fuzzy logic controllers (FLC) as well as the PID controller were compared in this study. THD content will significantly decrease as a result of this.
