“…A modulation method with reduced input current ripple can be used for the converter [5]. The fault detection methods for the inverter circuits and diagnosis algorithms for matrix converter can be carried out fast and simply [8][9][10]. Once the open-circuited fault occurs in one phase on an inverter circuit, such as open switch fault, open-phase fault and so on, it is detected immediately.…”

A fault-tolerant mechanism including topology and control strategy for multi-drive system based on indirect matrix converter is proposed in this paper, which is used for the remedial operation in case of opened switch faults and single-phase open-circuit on one of inverter circuits. Since there are a large number of switches in a multi-drive system based on indirect matrix converter, the fault-tolerant operation is achieved by reconfiguring the indirect matrix converter topology with a connecting device. Based on the reconstructed converter structure, a fault-tolerant modulation algorithm is developed to maintain ideal input/output currents and continuous driving operation. The proposed mechanism ensures improved system reliability and fault-tolerant capability without any backup leg or parallel redundancy. Simulation results verify the feasibility and validity of the proposed fault-tolerant mechanism for multi-drive system based on indirect matrix converter.

“…The steady state and dynamic response of a PMSM drive to a single phase open-circuit fault is investigated in [3]. In addition, two alternative post-fault control strategies are studied: opening all of the inverter switches and shorting the two remaining unfaulted phases together using the inverter switches.…”

The aim of this paper is to present an overall analysis of a typical permanent magnet synchronous motor drive under different operating conditions. Single power switch opencircuit faults as well as single phase open-circuit faults are introduced in the inverter and their effects are investigated trough a drive global performance evaluation. This includes the study of phase currents and voltages harmonic distortion and power factor on the mains supply side, the DC bus current, power losses and efficiency of the rectifier as well as of the system comprising the inverter and the motor. In addition, total drive efficiency values are also reported. Experimental and simulation results under these faulty operating conditions are presented, as well as results under healthy operating conditions, with the objective to establish a reference for comparison.

“…Researchers in references [7]- [10] have used various models or computer simulation techniques to detect faults in PM motors. A modified dq model, which used current rather than flux linkages as state variables, is presented in [9] for visualizing the effects of single phasing in IPM motors. The computer simulation is performed in [10] to investigate the effects of inverter faults on voltages, currents, and torques of the IPM motor during the flux-weakening mode of operation.…”

This paper presents an on-line protection scheme for three-phase interior permanent magnet (IPM) motors using artificial neural network. The proposed protection scheme is developed and implemented in real-time using the ds1102 digital signal processor (DSP) board. In this work, a two-layer feed-forward neural network (FFNN) with sixteen inputs and single output is designed and trained off-line with experimental data using the back-propagation algorithm. An experimental setup is developed to accommodate the on-line testing and to carry out the protection of IPM motors. Three types of faults such as single line to ground (L-G) fault, line-to-line (L-L) fault, and single phasing fault are investigated. The technique is evaluated and tested on-line on the laboratory 1-hp and 5-hp IPM motors using the DSP board. The laboratory results show that the proposed technique is able to detect the faulted conditions with high accuracy.
