In this research study, the feasibility of using one of the Hybrid Permanent Magnet (HPM) machine topologies acting as a generator with a passive rectification stage is considered. The primary application area is in the power-train of a series hybrid electric vehicle where the concept will be considered as an alternative to brushless PM machines interfacing to the vehicle power-train via active power electronic converters. The electro-magnetic design of the two main parts in the selected HPM generator topology and their individual system behaviour at normal and rated conditions will be studied. Prediction of the transient and steady state temperature in some of the HPM machine parts will be conducted based on commercial thermal analysis software. Two HPM machine stator winding configurations; 3-phase and 9-phase, with their relevant passive rectification stages will be analysed in terms of their terminal and DC-link output power along with the quality of the generated DC output voltage. An investigation of the operational characteristic of the HPM generator when delivering a fixed power at a fixed speed into a dynamic DC voltage source typical of a hybrid electric vehicle power-train subject to urban driving regimes will be presented. The research work will be a mixture of simulation studies using electro-magnetic finite element analysis (FEA), transient machine and system analysis via SimPower, a Matlab/Simulink toolbox set, along with test validation via a representative prototype HPM generator configuration and its interface to an experimental electrical system evaluation platform.
