Abstract :
This paper presents an iterative finite-element analysis (FEA) approach for the design of integrated electric drives comprising of interior permanent magnet fractional-slot concentrated winding (IPM-FSCW) machines and the stacked poly-phase bridges (SPB) converter. Particular focus is put on fault tolerance to handle a shorted converter submodule and the level of fault tolerance versus compactness (torque density) and power factor is quantified in the form of a case study considering a 30 kW, 2000 rpm machine.
