“…This paper aims to address the above challenge to some extent by proposing the open-ended winding induction motor (OEWIM) [18]. A conventional IM can be operated as OEWIM without any modification by powering its two ends of the stator winding separately through two voltage source inverters (VSI) [13], [19], [20]. The OEWIMs are successfully employed in [19]- [21] and have following advantages over single ended convention IM.…”

“…4) In OEWIM, better current THD and reduced torque ripple can be obtained even with reduced switching frequency [21]. 5) OEWIM has higher reliability due to inherent fault tolerant capability and absence of neutral-point variations [13]. However it should be noted that OEWIM dives suffer from some disadvantages such as increased switching loss, increased losses due to zero sequence current, and zero sequence voltages and power sharing between two inverters.…”

“…For EV, the control of the propulsion system depends on the inverters. These inverters can fail due to vibration, disconnection errors and device failure [13].

This paper presents a new open-ended winding induction motor (OEWIM) based dual-motor differential fourwheel drive (D4WD) for the electric vehicle (EV). Constant speed operation through cruise control is achieved using direct torque control (DTC) algorithm. The redundant vectors are used in the switching vector selection of the DTC algorithm to achieve balanced battery currents. Fault-tolerant operation of the drive is demonstrated, where the EV will work with full torque even if one of the inverters in rear motor drive or front motor drive or both fail. The dynamic model of the proposed drive is presented. The proposed drive and fault-tolerant operation (FTO) is verified through simulation as per the FTP-75 driving cycle. An experimental prototype of the proposed drive is developed, and the above algorithms are verified experimentally as per the FTP-75 and HFET driving cycles. Both the simulation as well as the experimental results are presented, and these results agree with the theoretical observations. Stable operation of EV for the entire test cycle under normal operation, as well as inverter fault conditions, is demonstrated.

Summary Dual‐inverter‐driven open‐end winding brushless direct current motor (OEWBLDCM) drives are amenable for the implementation of some interesting fault‐tolerant features, which could find useful applications in low power electric vehicles (EVs). The power semiconductor switching devices in the dual‐inverter system are vulnerable to the development of open‐circuit faults (OCFs) and the short‐circuit faults (SCFs). This paper investigates the possibility of imparting complete fault‐tolerant capability to EVs, which employ OEWBLDC motors for propulsion. With the proposed dynamic post‐fault reconfiguration of the power circuit and the reconnection of the battery banks, it is possible to deliver the rated (i.e., 100%) post‐fault output power to the BLDC motor, despite the failure of a power semiconductor switching device (because of either an OCF or an SCF) in the dual‐inverter system. The feasibility evaluation of the proposed fault‐tolerant drive reveals that the aforementioned objectives are realizable at an affordable hike in the raw material cost of the propulsion system. Simulation studies and Experimental verification on a laboratory prototype validate the proposed fault‐tolerant OEWBLDCM drive.

As the most favorable candidate of electric vehicle drive system, the fault tolerance of open‐end winding permanent synchronous motor (OEW‐PMSM) fed by dual inverter with common DC bus is of great significance because it is related to the reliability and safety of the system. Aiming at the most common fault of open‐phase, a fault‐tolerant operation strategy based on 60° phase difference current control is proposed by making full use of the characteristics that each phase of OEW‐PMSM can be controlled independently. Through this method, the same stator rotating magnetic field can be generated before and after the open‐phase fault without reconfiguring the controller, so as to reduce the torque ripple after the fault and ensure the continuous and stable fault‐tolerant operation of the motor. In addition, this method can reduce the switching times by 50%. The proposed method can reduce the switching loss by 50% compared with the ordinary modulation method, reduce the switching loss, and will not produce large zero sequence current. Experimental results show that the fault‐tolerant performance of this strategy is significantly improved compared with the traditional methods.
