Abstract

In this paper, a closed-form expression to estimate the overlap angle in a slip energy recovery system is presented. The prediction of the overlap angle is important in the case of doubly-fed induction motor drives, because of its influence on speed and torque. A closed-form expression is derived using a hybrid model of the induction motor and a dynamic model of the rotor rectifier. The ripple content of the dc link current and the inverter input voltage are neglected. The predicted results obtained using the closed form expression are verified experimentally.
