摘要：
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 connected to an uncontrolled bridge rectifier. Two winding and rectifier topologies are considered: a three-phase winding with a three-phase bridge rectifier and a double three-phase winding with a three-phase rectifier each, connected in series. Both magnet flux tooth ripple and stator magneto-motive force 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 three-phase windings was found to have considerably lower rotor losses than the machine with one single three-phase winding.
