An annoying tonal noise is produced by modern electrical trains during acceleration and deceleration. This noise is caused by electromagnetic forces generating structural vibrations, especially from the traction motors. The electromagnetic noise is dominant at low train speeds and affects both the passengers on the train and on platforms, as well as people living near the track. The focus on th...

The emergence of silicon carbide(SiC-) based power semiconductor switches with their superior features compared with silicon (Si) based switches has resulted in substantial improvements in the performance of power electronics converter systems. These systems with SiC power devices are more compact, lighter, and more efficient, so they are ideal for high-voltage power electronics applications, i...

Integrated chargers, where the traction inverter is used as primary charging interface, have emerged a solution for reducing cost and footprint of electric vehicle (EV) charging. This article proposes bidirectional nonisolated integrated charger topology that also provides benefits to motor lifetime reliability through reduction in bearing currents voltages. achieved by adding an EV drive: <inl...
