Machine and inverter loss minimization of hybrid excited permanent magnet synchronous machines for electric vehicles
This paper discussed a control system for an HPMSM machine with a stator based field coil aiming at maximum efficiency of the inverter machine system. A new procedure for efficiency optimal inverter machine propulsion system has been introduced. An iterative process for optimal current distribution is described with multidimensional tables of overall losses and efficiencies. Due to high speed calculations, optimization algorithm can be implemented for various goal functions including classic PMSM drivetrains.
