本文介绍并分析了使用 800V 电池的新一代电动汽车的潜在高压辅助动力单元 (APU) 架构。该架构是基于提供 400V 和 12V 直流总线端子而开发的，同时还为 APU 配备了集成板载 2 级充电器。设计过程的基础是最大限度地减少组件总数，同时在充电模式下保持电网和电池之间的电流隔离。不同的潜在架构在组件数量和效率方面进行比较；选择具有上述特征的合适拓扑。所选拓扑的性能通过仿真进行验证。
This paper presents and analyzes potential high voltage auxiliary power unit (APU)architectures for a new generation of electric vehicles which uses an 800V battery. The architectures are developed based on providing 400V and 12V DC bus terminals while also equipping the APU with an integrated on-board Level 2 charger. The design procedure is based on minimizing the total number of components while maintaining galvanic isolation between the grid and the battery in charging mode. Different potential architectures are compared in terms of number of components and efficiency and by doing so; a suitable topology with the aforementioned features is selected. The performance of the selected topology is verified through simulations.
