AI中文摘要:
典型的共总线结构及其固有的总线稳定要求,会成为电池供电自主系统电源灵活性的瓶颈,限制了可扩展性与即插即用能力。功率包技术通过对物理隔离的功率流进行时分复用,消除了共总线,从而克服了这一问题。然而,传统功率包路由器面临两个物理层局限:传输方向不可控,以及每个功率包的能量大小可控性有限。本文提出一种完全可控的双向功率包传输方案以解决这些局限。我们引入了一种包含并联电感作为临时能量缓冲器的路由器间电路,可实现任意方向的功率传输并完全控制传输能量。我们推导了路由器执行此操作的开关算法,并通过原型硬件实验验证了其可行性。
英文摘要:
The typical common-bus structure and its inherent bus stabilization requirement can become a bottleneck for flexibility in power supplies for battery-powered autonomous systems, limiting scalability and plug-and-play capability. Power packetization overcomes this by eliminating the common bus through time-division multiplexing of physically isolated power flows. However, conventional power packet routers face two physical-layer limitations: uncontrollable transmission direction and limited controllability of the amount of energy per packet. This paper proposes a fully controllable bidirectional power packet transmission to address these limitations. We introduce an inter-router circuit featuring a parallel inductor as a temporary energy buffer, enabling power transmission in any direction with full control over the transferred energy. We derive the switching algorithm for the routers to perform this operation and verify its feasibility through experiments using prototype hardware.
