Abstract

A Direct Torque control algorithm which enables the Doubly Fed Induction Motor (DFIM) to operate in constant torque region is proposed here. This algorithm is employed for EV/HEV application. Inverters are supplied by a MPPT enabled PV and battery. Torque and air-gap flux of a DFIM can be controlled directly.
