“…This system allows bidirectional operation with the power grid, and since it uses a six-phase machine, it allows a battery charging power twice that of the traction power, as well as having fault tolerance capability. In 2021, the same authors proposed a similar system based on a nine-leg inverter and a three-phase nine-winding machine [47], as well as giving a detailed analysis of the design of this type of machine for use in IBCs [48]. to accommodate the connection to a three-phase ac power grid and thus allowing fast battery charging [45].…”

Electric vehicles (EVs) contain two main power electronics systems, namely, the traction system and the battery charging system, which are not used simultaneously since traction occurs when the EV is travelling and battery charging when the EV is parked. By taking advantage of this interchangeability, a single set of power converters that can perform the functions of both traction and battery charging can be assembled, classified in the literature as integrated battery chargers (IBCs). Several IBC topologies have been proposed in the literature, and the aim of this paper is to present a literature review of IBCs for EVs. In order to better organize the information presented in this paper, the analyzed topologies are divided into classical IBCs, IBCs for switched reluctance machines (SRMs), IBCs with galvanic isolation, IBCs based on multiple traction converters and IBCs based on multiphase machines. A comparison between all these IBCs is subsequently presented, based on both requirements and possible functionalities.

“…However, contrary to the MSS structure, the HCS structure presents large mutual inductances between each winding set. They are namely in the order of their self inductances [29], which is specific regarding the other segmented drives [19]- [21] and mars the effectiveness of the feed forward compensation, even in a healthy mode (Table I). As a matter of fact, the traditional MDQF control structure requires to combine the HCS structure with additional external coupled inductors [24].…”

“…A recent international patent suggests an alternative segmentation option enabling to extend the drive modularity level up to the theoretical limit of the winding turn [11]. As such, this innovative architecture, referred to as the HCS, allows a full degree of freedom in the sizing of current and voltage ratings [28], [29]. It also facilitates the integration of the power converters close to the motor windings, thus limiting electromagnetic compatibility issues and boosting inverters heat power transfer.…”

This article addresses the control issue of a structure enabling the segmentation of three-phase electric drives. The proposed segmentation process offers an additional degree of freedom in terms of voltage rating for power electronics but results in a three-phase system with highly coupled sub-windings. Thus, for such a segmented motor, the true challenge lies in controlling the machine global electromagnetic torque while balancing the power among the different inverters. To tackle this issue, the dq standard synchronous frame is extended to common and differential modes. This approach enables to design a suitable control structure based on an analytical model and physical considerations. The developed model is calibrated with realistic numerical values obtained from a finite element analysis. Finally, an experimental setup allows developing a proof of concept which shows the interest of the proposed control method compared to a standard multiple dq-frame method. The key finding is that the above-mentioned control objective of the segmented synchronous motor can be achieved without additional inductors and despite the severe constraint imposed by such highly coupled segmentation.

“…In this paper, the bidirectional AC/DC converter has the function of PFC and supports the more considerable charging power due to the use of three-phase charging. The proposed studies realized integration by using the special motors (such as the multiphase motor [8]- [11], the switched reluctance motor [12], [13]) or by changing the internal structure of the motor (such as split winding [14]- [16], open winding motor [17]- [19]). These motors or motor structures are not widely used in EVs.…”

Motor driving technology and battery charging technology are the two core technologies of electric vehicles (EVs). They have a profound impact on the performance and mileage of EVs. Based on the topology of a traditional EV motor controller, this study employs the time-sharing multiplexing insulated gate bipolar transistor (IGBT) power module form to expand the functions of the motor controller. This paper proposes an integrated driving-charging controller structure that enables the controller to realize the motor driving and on-board charging simultaneously. A decoupling analysis was performed at the topology level, mathematical models of two bidirectional converters in the integrated topology were established, and a reasonable control strategy for the double-closed-loop control system was designed. The simulation system was built in Simulink, and the simulation results verified the effectiveness of the system topology and control strategy. We made an integrated controller experimental platform based on TMS320F28335. A resistive load simulated the power battery to verify the charging mode, and a 5kW permanent magnet synchronous motor (PMSM) was used to verify the driving mode. The experimental results demonstrated the driving-charging integrated controller's feasibility for electric vehicles.INDEX TERMS on-board charger, driving-charging integration, bidirectional AC/DC converter, bidirectional DC/DC converter.
