To provide a power supply transmission system capable of reducing the number of electric wires for connecting a power supply device to a load and suppressing an increase in power loss due to voltage conversion, when power is supplied from the power supply device to the load that requires a plurality of power supply voltages.SOLUTION: A plurality of power supply voltages are periodically and alternately switched and sent from an upstream side to a downstream side as an output voltage Vout1 of one system. On the downstream side, a plurality of voltages are respectively separated from the input voltage Vout1 and supplied to the load side. The voltage Vout1 is monitored on the downstream side to determine a switching timing. On the downstream side, capacitors 27 and 28 are provided for each voltage system to store electricity, and the voltage is maintained even while power supply from the upstream is interrupted. The low voltage required by a CPU 26 and the like on the downstream is generated by a voltage regulator 25 and the like on the downstream side. Loss when generating the power consumed by a load 32 having the low-voltage can be reduced.SELECTED DRAWING: Figure 1
【課題】複数の電源電圧を必要とする負荷に対し電源装置から電力を供給する場合に、これらを接続する電線の本数削減を可能にすると共に、電圧の変換に伴う電力損失の増大を抑制すること。【解決手段】複数の電源電圧を周期的に交互に切り替えて、1系統の出力電圧Vout1として上流側から下流側に送出する。下流側では、入力された電圧Vout1から複数の電圧をそれぞれ分離して負荷側に供給する。下流側で電圧Vout1をモニタして切替のタイミングを決める。下流側では電圧の系統毎にコンデンサ27、28を設けて蓄電し、上流からの電力供給が途絶えている間も電圧を維持する。下流側のCPU26等が必要とする低い電圧は、下流側の電圧レギュレータ25等で生成する。低圧の負荷32が消費する電力を生成する際の損失を低減できる。【選択図】図1
