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.
