Optimal Control of Voltage Source Inverters Supplying Induction Motors

Abstract The paper is concerned with the voltage source inverters ensuring the minimization of additional coil losses in the induction motor. Both simple and PWM inverters will be considered under non-modified control. Theoretically, the results are only valid if the skin effect in the motors is neglected. Nevertheless, the results as first approximation prove to be valid even for motors with relatively strong skin effect.
