基于电力电子电路拓扑的新型总线供电/通信技术

本文提出了一种新型的总线供电/通信电路的设计方法。该方法根据电力电子电路基本拓扑，推导相应的总线供电/通信电路。根据该方法设计了Buck 型总线供电电路，实现了在单一总线上同时传输电源和信号。并对其
工作原理，以及在连接传输线时的稳态和动态开关特性做了详细分析，给出了计算方法。最后通过实验电路验证了该方法的正确性。
Abstract: This paper presents a new method of designing novel powered bus circuits, which transmit power and data through a single bus. This method is based on power electronics topology and can induce to find out application circuits. The principle of the Buck-type powered-bus circuit is introduced, and under the condition of connected by transmission line, the steady-state characteristics of the circuit as well as dynamic switching characteristics are analyzed in detail. At last, the effectiveness of this method is verified by experimental result.
