Design and Multi-Objective Optimization of a 12-Slot/10-Pole Integrated OBC Using Magnetic Equivalent Circuit Approach

Permanent magnet machines (PMs) equipped with fractional slot concentrated windings (FSCWs) have been preferably proposed for electric vehicle (EV) applications. Moreover, integrated on-board battery chargers (OBCs), which employ the powertrain elements in charging process, promote zero-emission future envisaged transportation through transition to EVs. Based on available literature, employed machine, as well adopted winding configuration, highly affects performance of OBC. However, optimal design FSCW-based PM machine mode operation has not conceived thus far. In this paper, and multi-objective optimization an asymmetrical 12-slot/10-pole OBC based efficient magnetic equivalent circuit (MEC) approach are presented, shedding light during mode. An ‘initial’ surface-mounted (SPM) is first designed model. Afterwards, a genetic algorithm utilized define parameters. Finally, compared using finite element (FE) simulations order validate highlight superiority over its initial counterpart.
