In this paper, the basic principle of the conventional slip energy recovery induction motor drive is discussed. Two kinds of slip energy recovery induction motor driving systems with high factors are discussed, and the performance analysis of these methods is compared. On the basis of above, a new type of three-phase and four-line slip energy recovering drive is proposed.
