“…The filter design has been well developed in recent years. Pairodamonchai et al suggested a hybrid output EMI filter to eliminate the high-frequency CMV components [168], and the researches on the optimization of filters have also been reported [169,170]. Moreover, an advanced inverter design can also help to reduce CMV: The active zero state PWM (AZSPWM) method [171] and the near state PWM (NSPWM) method [172] effectively suppress the neutral voltage of a motor.…”

In modern electric equipment, especially electric vehicles, inverter control systems can lead to complex shaft voltages and bearing currents. Within an electric motor, many parts have electrical failure problems, and among which bearings are the most sensitive and vulnerable components. In recent years, electrical failures in bearing have been frequently reported in electric vehicles, and the electrical failure of bearings has become a key issue that restricts the lifetime of all-electric motor-based power systems in a broader sense. The purpose of this review is to provide a comprehensive overview of the bearing premature failure in the mechanical systems exposed in an electrical environment represented by electric vehicles. The electrical environments in which bearing works including the different components and the origins of the shaft voltages and bearing currents, as well as the typical modes of electrical bearing failure including various topographical damages and lubrication failures, have been discussed. The fundamental influence mechanisms of voltage/current on the friction/ lubrication properties have been summarized and analyzed, and corresponding countermeasures have been proposed. Finally, a brief introduction to the key technical flaws in the current researches will be made and the future outlook of frontier directions will be discussed.

“…In the literature, various filter design methods [7]- [10] or PWM techniques [11]- [13] have been studied in efforts to reduce the CM voltage noise. While some research has also proposed active CM noise cancellation [14]- [16], there has been a lack of innovation regarding topologies for the minimization of CM EMI noise, but as WBG devices become more prevalent, this will become more important.…”

Wide bandgap (WBG) semiconductor power devices are becoming increasing popular as an alternative to conventional Si devices in power applications. While these WBG devices have many inherent benefits, one downside of these devices is the potential for increased emission of electromagnetic interference (EMI) due to the increased switching frequency and turn-on/off capabilities. To mitigate this effect, this paper presents a novel inverter topology to reduce the source of the common mode EMI noise, thus, potentially reducing the required EMI filter size. In this study, the novel topology is implemented as a three-phase voltage source inverter utilizing GaN HEMTs, and is simulated with circuit simulation software LTSpice with device models provided by manufacturer, and results are analyzed with MATLAB. A characterization of the key design parameters for the novel topology is also provided.

As many industries look to wide bandgap (WBG) devices to replace Si devices in power applications, their effects on the power converter need to be first understood in full. While the benefits of WBG devices are widely known, including high switching frequency operating capability, the special characteristics of these new devices have the potential to cause other issues, in particular electromagnetic interference/ compatibility (EMI/EMC). In this paper, multiple EMI filter topologies are investigated for a motor drive system utilizing WBG devices, GaN HEMTs. The different topologies are simulated using LTSpice circuit simulation software and the results are analyzed and complied with MATLAB. The tradeoffs of different filter topologies, namely attenuation versus efficiency and ground current, are demonstrated, providing crucial information for system level designers implementing WBG power switching devices.
