In automotive applications, efficiency of the drive train is very important due to the limited energy in the battery. Improvement can be achieved by increasing the inverter output voltage through overmodulation. This can be used for either increasing output power or reducing power losses. This paper presents a new strategy of voltage limitation for the current control of three-phase electric drives. The proposed limitation scheme allows the use of dynamic rotor-oriented current control with no modifications for operation in overmodulation range. The novel limitation structure is described and verified through simulations and experimental results.
