2. Slotless High-Performance Electric Drives : Harmonic Loss Analysis, Sensorless Control, and Inverter Design
Abstract : Electric motor drives are a cornerstone for many fundamental functions in today’s society, and their expected dominance within the transport sector is considered one of the main keys to abate global warming. Subsequently, the incentives for improved performance of electric motor drives cannot be sufficiently emphasized. READ MORE

3. Harmonic Mitigation in Traction Drives
Abstract : In railway traffic the low friction between wheel and rail causes long braking distances, normally much longer than the sight distance of the driver, i.e. if the driver starts the braking when a problem on the track is discovered, it might be too late to brake the train. Therefore, safe railway traffic can not only rely on the driver. READ MORE
