Integrated on-board battery chargers (IOBCs) have shown promise as an elegant charging solution for electric vehicles in recent literature. Although the three-phase charging technique of IOBCs has extensively been discussed in the literature, single-phase charging is still a challenging research topic. The predictive current control (PCC) approach has shown many benefits, including a straightforward algorithm, simple implementation, comparatively quick response, and appropriate performance, when compared to conventional control techniques. This article investigates the impact of single-phase charging of a six-phase-based IOBC system with different winding configurations using PCC, which, up to the best of our knowledge, has not been conceived thus far. Under single-phase charging, the zero-sequence current component is utilized to ensure zero torque production during charging mode. Since the impedance of the zero subspace is highly affected by the employed winding design, the performance of PCC with different winding layouts of either induction machine (IM) or permanent magnet synchronous machine (PMSM) is investigated and compared. The proposed method is experimentally validated using a 1.1-kW six-phase IM and a 2-kW 12-slot/ten-pole PMSM. Finite-element analysis is also carried out to investigate the effect of the single-phase charging mode on the induced radial forces and vibration level when the PM machine is employed.
