   Performance of Diagnosis Methods for IGBT Open Circuit Faults in Three Phase Voltage Source Inverters for AC Variable Speed Drives
By FUCHS Friedrich Wilhelm; ROTHENHAGEN Kai [View]
[Download]

Abstract: Variable speed drives have become industrial standard in many applications. Therefore fault diagnosis of voltage source inverters is becoming more and more important. One possible fault within the inverter is an open circuit transistor fault. An overview of the different strategies to detect this fault is given, including the algorithms used to localize the open transistor. Previous work showed significant differences among the available methods to detect such a fault for a mains side active rectifier. This paper extends the performance evaluation for the inverter connected to the machine with variable stator voltage and frequency. Simulation results are presented. They show the influence of the applied standard field oriented control on the currents during a fault. An experimental setup in the laboratory is used to validate simulation results. Typical detection results are presented including time-to-detection measurements. Robust detection of open transistor faults has been found to be possible.

   REAL-TIME FAULT DETECTION AND LOCALIZATION IN VECTOR-CONTROLLED INDUCTION MOTOR DRIVES
By SLESZYNSKI Wojciech; CICHOWSKI Artur; NIEZNANSKI Janusz [View]
[Download]

Abstract: This paper addresses real-time diagnostics of vector-controlled induction motor drives. The fault type considered is the open transistor in the voltage source inverter (VSI). The proposed methods are capable of diagnosing both permanent failures and short-time faults of inverter transistors. They require no extra hardware on top of that normally used for basic control purposes. The methods have been verified by simulation and laboratory experiments.

   Wireless technologies in condition monitoring and remote diagnostics of electric drives; requirements and applications
By LINDH Tuomo; SARKIMAKI Ville; AHOLA Jero; TIAINEN Risto [View]
[Download]

Abstract: This paper concentrates on utilization of wireless technologies on the data transfer needs of condition monitoring, maintenance and remote diagnostics of electric drives. A short introduction to typical short-range radio technologies is given. Requirements for wireless technologies in condition monitoring are discussed. The main focus is the introduction of different applications that the use of short-range wireless technologies makes possible.
