Rotor eddy current power loss in permanent magnet synchronous generators feeding uncontrolled rectifier loads
Rotor eddy current power loss in permanent magnet synchronous generators feeding uncontrolled rectifier loads
Analytical methods and transient finite element analysis (FEA) with rotating mesh are used to calculate rotor eddy current power loss in a permanent magnet synchronous generator (PMSG) connected to an uncontrolled bridge rectifier. Two winding and rectifier topologies are considered: a 3-phase winding with a 3-phase bridge rectifier and a double 3-phase winding with a 3-phase rectifier each, connected in series. Both magnet flux tooth ripple and stator MMF harmonics are considered in the calculation of rotor loss; the harmonics are added vectorially. Good agreement is observed between analytical and FEA for constant dc link current and constant voltage loads. The machine with double 3-phase windings was found to have considerably lower rotor losses that the machine with one single 3-phase winding.

Abstract
Analytical methods and transient finite element analysis (FEA) with rotating mesh are used to calculate rotor eddy current power loss in a permanent magnet synchronous generator (PMSG) connected to an uncontrolled bridge rectifier. Two winding and rectifier topologies are considered: a 3-phase winding with a 3-phase bridge rectifier and a double 3-phase winding with a 3-phase rectifier each, connected in series. Both magnet flux tooth ripple and stator MMF harmonics are considered in the calculation of rotor loss; the harmonics are added vectorially. Good agreement is observed between analytical and FEA for constant dc link current and constant voltage loads. The machine with double 3-phase windings was found to have considerably lower rotor losses that the machine with one single 3-phase winding.
