“…Typically, the detection speed of a current-based algorithm depends on the time instant of the fault occurrence [24]. Specifically, if a fault occurs in the bottom IGBT and during the negative current half-cycle of the respective phase, the effect can be immediately seen since the current tends to be zero.…”

Abstract:To improve the diagnostic detection speed in electric vehicles, a novel diagnostic algorithm of insulated gate bipolar transistor (IGBT) open circuit faults for power inverters is proposed in this paper. The average of the difference between the actual three-phase current and referential three-phase current values over one electrical period is used as the diagnostic variable. The normalization method based on the amplitude of the d-q axis referential current is applied to the diagnostic variables to improve the response speed of diagnosis, and to avoid the noise and the delay caused by signal acquisition. In the parameter discretization process, the variable parameter moving average method (VPMAM) is adopted to solve the variation of the average value over a period with the speed of the motor; hence, the diagnostic reliability of the system is improved. This algorithm is robust, independent of load variations, and has a high resistivity against false alarms. Since only the three-phase current of the motor is utilized for calculations in the time domain, a fast diagnostic detection speed can be achieved, which is significantly essential for real-time control in electric vehicles. The effectiveness of the proposed algorithm is verified by both simulation and experimental results.

“…A detailed review of the recent literature on inverter FD is developed in [79]. Reference [80] notes the characteristics of each of the two main types of switch failures in inverters: while short-circuit fault are typically very destructive and require the adoption of actions to shut down the drive immediately, open-circuit faults do not necessarily lead to system shutdown and can remain undetected for a long time (however, such faults can lead to secondary faults in other converter components that can eventually lead to high repair costs) [80].…”

“…Furthermore, in some drive applications such as vehicle and railway transportation, a high degree of reliability and safety must be continuously achieved, even in accident or fault situations, which makes the fault diagnosis of AC machine drive systems as one of the primary concerns [1]. Since a fault in such applications Also, the fault detection based on the average absolute values of normalized currents has been presented to implement the detection irrespective of operating conditions [19,20]. Other studies have considered the simultaneous open faults in inverter multiple switches and detected fault occurrence by using the current harmonics [1,21], moving window-based current signals [22], and non-zero phase current information [23].…”

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.
