A novel induction motor direct torque control (DTC) algorithm with synchronous modu-lation is presented. Compared to the traditional DTC method, whose main drawback is the presence of low‐frequency torque harmonics (sub‐harmonics), in the proposed method, the PWM switching frequency is imposed to be an integer multiple of the main supply...

High switching frequency employed in modern power electronic converters is cause of important common mode electrical quantities, having as consequences the premature motor failure and other unwanted effects in drive systems. A new SVM scheme for cascaded multilevel converter, aimed to the attenuation of these consequences, is proposed.
