Commercially available hybrid and electric vehicles are generally using rare earth PM motors because of their compactness and very good efficiency. But the supply security and price volatility of rare-earth materials are still major concerns for the hybrid and electric vehicle industry. Hence, global efforts are underway in several countries on using reduced or non-rare earth materials, developing...
Important global efforts are underway toward lowering the cost of electric machines for electric and hybrid vehicles by reducing or eliminating the use of rare earth materials which have been experiencing significant price increases and volatility. Non-permanent magnet electric machines are a potential solution and are increasingly investigated by researchers worldwide. This paper presents a DC biased...
This study focuses on developing fast, easily implementable minimum loss space vector pulse-width modulation (PWM) algorithms for three-level inverters that can work through extended region of operation into over modulation. A unique way of duty cycle limitation for the maximum dc bus utilisation and the minimum loss PWM techniques is organised in the algorithm in a way to require minimum cycle time...
Producing the required magnitude and shape of reference current is necessary to achieve precise torque control in motor control applications. A deadbeat predictive current controller provides very good dynamic performance. In order to achieve very accurate reference current production, the machine and inverter should be modelled properly with accurate parameters. Parameter changes, especially the...
