Abstract In order to improve the reliability and safety of the motor drive system, an open-end winding induction motor (OWIM) driver with single-stage boost and fault-tolerant function is proposed in this paper. The topology of the driver system combines with impedance source network and 3-H bridge inverter, which can realize single-stage boost function and fault-tolerance under the condition when the inverter occurs fault. According to the rule of inserting shoot-through zero vector and the space vector pulse width modulation (SVPWM) method of 3-H bridge inverter, the SVPWM method of normal and fault-tolerant operation for the single-stage Boost 3-H bridge inverter is proposed and analyzed in detail. Finally, the experimental platform of OWIM is built to validate the analysis of the modulation method is correct and the OWIM drive system has boost function and fault-tolerance ability.

Key words： Fault-tolerant operation open-end winding induction motor (OWIM) single-stage Boost 3-H bridge inverter
