The purpose of the present invention is to achieve redundancy of a power supply function with a simple configuration, and to ensure the continuity of operation at the time of a failure. A power supply network (1) is provided with: a first power supply path (20-1) that is connected to a vehicle host drive power source (100-0) via a power conversion device (101) and that is connected to loads (40-1, 41, 42-1); and a second power supply path (20-2) that is connected to a power supply source (100-2) different from the host drive power source (100-0), that is connected to the loads (40-2, 41, 42-2), and that is connected to the first power supply path (20-1) via the switch (SW0). The switch (SW0) is closed when the first power supply path (20-1) and the second power supply path (20-2) are normal, and is opened when the first power supply path (20-1) or the second power supply path (20-2) is abnormal.
本发明的目的在于,通过简单的结构实现供电功能的冗余性,能够确保故障时的动作持续性。供电网(1)包括:第1供电路径(20‑1),其经由功率转换装置(101)与车辆的主机驱动用电源(100‑0)连接,并且与负载(40‑1、41、42‑1)连接;以及第2供电路径(20‑2),其与不同于主机驱动用电源(100‑0)的供电源(100‑2)连接,并且与负载(40‑2、41、42‑2)连接,且经由开关器(SW0)与第1供电路径(20‑1)连接。开关器(SW0)在第1供电路径(20‑1)及第2供电路径(20‑2)正常的情况下关闭,在第1供电路径(20‑1)或第2供电路径(20‑2)异常的情况下打开。
