“…The cost of the motor will also be higher because the neutral has to be brought out. If an application requires rated post-fault power then the phase current increases by factor of √3 [11]. Therefore the cost of each switching power device as well as dc bus filter capacitor increases by about 50%.…”

“…A number of motor and inverter configurations with differing degrees of fault tolerant capability for industrial and aviation applications have appeared in the literature [6][7][8][9][10][11][12][13]. Some include BLDC motor drives with concentrated phase windings where each phase is connected to an H-bridge inverter [6][7].…”

“…Remedial strategies for brushless DC motor drives' failures for specific faults have been addressed by monitoring phase currents and base drive signals of the power devices [10]. Inverter topologies with neutral leg and additional phase leg were presented with some intelligent control techniques to improve the fault tolerant capability of the drive for various types of faults [11][12][13]. These topologies use several additional power devices and passive components and may not be cost effective for automotive applications.…”

Future automobiles will be equipped with bywire systems to improve reliability, safety and performance. The fault tolerant capability of these systems is crucial due to their safety critical nature. Three fault tolerant inverter topologies for permanent magnet brushless dc motor drives suitable for automotive x-bywire systems are analyzed. A figure of merit taking into account both cost and post-fault performance is developed for these drives. Simulation results of the two most promising topologies for various inverter faults are presented. The drive topology with the highest post-fault performance and cost effectiveness is built and evaluated experimentally.

“…By using the fault signature developed by each seven fault group as well as by introducing free-wheeling mode detection, the open faults in multiple switches can be identified in a reliable and systematic way. In addition, rather than confining the number of simultaneous open-switches to only two, the proposed scheme aims to extend the open fault problem in multiple Energies 2018, 11,101 4 of 23 switches into a general case. The main objective is to realize a rapid and reliable online fault localization algorithm under the condition of simultaneous open-switches (up to three) without requiring any extra hardware or sensors in order that the algorithm can be easily installed in the main CPU of a commercial drive system.…”

Abstract:In order to overcome the limitations of conventional diagnosis methods, this paper proposes a reliable and practical on-line fault localization scheme for a pulse width modulation (PWM) inverter-fed permanent magnet synchronous machine (PMSM) drive system even when the inverter has simultaneous open faults in up to three switches. An open-switch fault is usually initiated by an accidental over-current, or electrical and thermal stresses. This fault may induce crucial secondary damage in the drive system since it is easily propagated and produces a continuous harmful effect on other system components. The open-switch faults in inverters often occur in a very complicated manner. Due to this reason, it was only recently that real-time diagnosis schemes under the open-switch faults in multiple switches have been presented in a few references. However, to alleviate the complexity and exactness issues, most of the conventional diagnosis schemes have considered the open faults only in two simultaneous switches until now, which is not generally the case. Even though the fault detection is simple and immediate, the exact fault localization is not a simple task, especially when there are open faults in three simultaneous switches because different open-switch fault locations may develop the same fault signature. To deal with such a problem, free-wheeling mode detection is introduced in this paper for the purpose of identifying the exact fault group and the faulty switch location. Then main objective of this paper is to realize a reliable fault localization algorithm under the condition of simultaneous open-switches (up to three) on an online basis without requiring any extra hardware or sensors in order that the algorithm can be easily installed in main CPU of a commercial drive system. For this purpose, the open faults in simultaneous switches are categorized into seven different fault groups. The entire system is implemented on a digital controller by using TMS320F28335 digital signal processor (DSP). The experimental results are presented under various open fault conditions to validate the usefulness of the proposed open-switch fault localization scheme.

“…However, neither simulation nor experimental results were presented. For the PM BLAC machine, an ELES scheme for fault tolerant control purpose, together with SVPWM, has been proposed for an interior permanent magnet (IPM) machine in [9][10]. This scheme introduced a feed-forward compensation scheme to the reference voltages to achieve high performance.…”

Reliability and fault tolerance of drive systems has received renewed research interest over last decade with several fault tolerant drive topologies and control schemes having been proposed and investigated. In this paper, the performance of hysteresis current vector control methodologies when applied to three common fault tolerant drive topologies has been investigated and compared theoretically and experimentally. Their advantages and limitations in terms of current value, current and torque ripples, and operating speed range etc. are considered and verified by both simulated and measured results. It is proven that by simply modifying the hysteresis current control methodology, the maximum torque per ampere (MTPA) can still be achieved in post-fault operation, albeit with potentially increased current value, low frequency current and torque ripples, and compromised speed operating range.
