Review of Key Technologies of Multi-phase Machine-based Electric-drive-reconstructed Onboard Chargers for Electric Vehicles
电驱重构型车载充电系统为电动汽车电气部分提供了一种全新轻量化设计思路,旨在利用电驱单元分时执行电驱与充电2种变流功能.相较于三相电驱系统,多相电驱系统具有输出转矩平滑、容错性能强等诸多优势特性.鉴于此,该文首先归纳现有并网式多相电驱重构型车载充电系统的拓扑结构与控制策略,并介绍其容错运行方案;然后,着重分析太阳能电动汽车用多能量端口电驱重构型车载充电系统的工作原理与控制策略;最后,总结全文并对多相电驱重构型车载充电系统的发展方向进行展望.
The electric-drive-reconstructed onboard charger provides a new lightweight design idea for the electric part of electric vehicles,aiming to utilize the electric drive unit to perform driving and charging operations separately at different moments.Compared with three-phase electric drive systems,multi-phase ones possess several merits,such as smooth output torque and fault tolerance.In view of the above,this paper first summarizes the topologies and control strategies of the grid-connected multi-phase electric-drive-reconstructed onboard chargers.Besides,fault-tolerant operation schemes of the grid-connected multi-phase electric-drive-reconstructed onboard chargers are introduced.Then,the operating principle and control strategy of multi-energy interface electric-drive-reconstructed onboard chargers for solar-powered electric vehicles are analyzed emphatically.Finally,conclusions are made,and the development direction of the multi-phase electric-drive-reconstructed onboard charger is outlined.
