The knowledge of the inherent common-mode voltage of voltage source inverters and its impact on the mechanical drive train elements is an important issue. With the help of model-based calculations it is possible to identify critical operating points. In addition to the influence of the converter, different operating conditions such as speed and temperature have a main influence on the resulting discharge...
Voltage source inverters in electrical drive systems are the main sources of possible mechanical degeneration inside the anti-friction bearings of downstream drive train components. In order to find the right countermeasures to avoid these parasitic effects, knowledge of the switching conditions of the converter and the subsequent effects are an important issue. This paper focuses on the converter's...
