Predictive Current Control Based Single Phase Charging of Six-Phase Integrated On-board Battery Charging System

In the past few years, Integrated On-Board Battery Chargers (IOBCs) have shown a substantial growth worldwide within the electric vehicles' market. Multi-phase machines have recently been favored thanks to their outstanding merits over three-phase counterparts. However, the optimum winding configuration and control technique remains a challenging topic. This paper proposes and compares three different six-phase winding configurations through single phase charging by connecting the two neutral points of the two three-phase sets to the single phase grid terminals. The system is controlled using Predictive Current Control (PCC), which has significant advantages, such as simple algorithm, easy implementation, relatively fast response, and adequate performance. This paper presents the detailed design and construction of three six-phase winding layouts which are fulfilled from an externally reconfigured lkW 12-phase induction motor. The designed system is experimentally validated to support the theoretical findings.
