摘要

A closed-form expression for estimating 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 results predicted by the closed-form expression are verified experimentally.
