This article represents research on fault diagnosis of inverter electric drives. It puts more emphasis on power electronics and drives. The paper begins with the diagnostics of systems with conventional inverter drives, because knowledge of the fault diagnosis in conventional inverter can be used for its applications in other topologies of inverter drives. Therefore, the article describes several methods for troubleshooting.

To improve the design of electric drives and to better predict the system performance, numerical simulation has been widely employed. Whereas in the majority of the approaches, the machines and the power electronics are designed and simulated separately, to improve the fidelity, a co-simulation should be performed. This paper presents a complete coupled co-simulation model of synchronous reluctance machine (SynRel) drive, which includes the finite element model of the SynRel, the power electronics inverter, the control system, and application examples. The model of SynRel is based on a finite element model (FEM) using Simcenter MagNet. The power electronics inverter is built using PLECS Blockset, and the drive control model is built in Simulink environment, which allows for coupling between MagNet and PLECS. The proposed simulation model provides high accuracy thanks to the complete FEA-based model fed by actual inverter voltage. The comparison of the simulation results with experimental measurements shows good correspondence.

Dem steigenden mechatronischen Integrationsgrad im elektrischen Antriebsstrang des Automobils wird mit neuartigen Kontaktsystemen begegnet. Unter Einsatz analytischer und numerischer Modellbildung sowie experimenteller Prüftechnik werden Leistungskontakte entwickelt, um hohe Energiedichten innerhalb der physikalischen Komponenten Traktionsmaschine, Leistungselektronik und Batteriespeicher zu übertragen.   The increasing level of mechatronic integration in the electric powertrain of automotive vehicles is overcome by innovative power connectors. Utilizing analytical, numerical and experimental procedures, high-current connectors are developed to transmit electrical loads within the key components electric motor, power electronics and battery system.
