The realize method of ITC strategy in FSTP induction generation system is studied. In order to improve stable performance of FSTP induction generation system, SVM-ITC (ITC based on space vector modulation) is investigated. Creation method of reference voltage vector which includes change trend and magnitude information of flux link and torque is presented. Because there is no zero voltage vector in four-switch system, a method which employs opposite vector in equal time to replace zero voltage vector is proposed. Two vector modulation schemes are presented.
