PERMANENT MAGNET MULTIPHASE MACHINE MODELING AND CONTROL FOR MV WIND ENERGY APPLICATIONS
… has been put into the modelling of electrical machines to provide mathematical models for control purposes. As the power electronics isolate the machine from the grid, the number of phases on both sides no longer needs to be the same, thus allowing for use of multiphase machines. Several …

PWM strategies for multilevel multiphase AC drives
… width modulation (PWM) strategies for multilevel multiphase ac drives have been analysed in this thesis. The large amount of published work in the area of multiphase drives recognises their advantages compared to the standard three-phase solutions. Some of them arc improved power sharing …

Multiple Three-Phase Induction Generators for Wind Energy Conversion Systems
… increase in the number of published works on multiphase machines and drives. This increased interest has been largely driven by a need for the so-called green energy, i.e. energy generated from renewable sources such as wind, and also an increased emphasis on greener means for transportation. …

Integrated on-board battery chargers for EVs based on multiphase machines and power electronics
… reason is the undesirable torque production in machines integrated into the charging process during the battery charging, which is unavoidable when a three-phase machine of either synchronous or induction type is used. The thesis investigates integrated on-board battery chargers for electric …

Analysis and Modelling of Fractional-Slot Concentrated-Wound Interior Permanent Magnet Machines
… (FSCW) interior permanent magnet (IPM) machines and establishes a basis for their magnetic and electrical analysis. In the state of the art methods for analyzing such machines, the non-homogeneous magnetic saturation and the non-linear B-H curve of the rotor iron are not considered. …
