Electric Drive Based on Double-Inverter-Fed Induction Machine with Minimization of Power Losses

摘要

An electric drive based on a double-inverter-fed induction machine is presented. The control system of the electric drive minimizes the electromagnetic losses both at constant flux linkage in the gap and during its regulation at the optimal level. The considered variant of control permits one to significantly increase the acceptable electromagnetic torque during two-region rate regulation and to improve the energy characteristics.
