This auxiliary power supply unit (1) is provided with an auxiliary power supply device (71) and a downstream-side power supply line group (72) that connects the auxiliary power supply device to motor units (13, 32). An auxiliary power supply device (71) is provided with: an auxiliary power supply (111) provided in a power supply path to assist power supply from an external power supply (45) to a motor unit; and a switching circuit (114) configured to switch a connection state of the auxiliary power supply with respect to the power supply path. The connection state of the auxiliary power supply includes a boost state in which the auxiliary power supply and the external power supply are connected in series between the external power supply and the motor unit. The downstream-side power supply line group (72) includes branch first downstream-side drive lines (161, 162) and branch second downstream-side drive lines (163, 164). The upstream-side ends of the branch first downstream-side drive line and the branch second downstream-side drive line are connected to the power supply path on the downstream side of the auxiliary power supply.
本发明的辅助电源单元(1)具备辅助电源装置(71)和下游侧供电线组(72),下游侧供电线组(72)将辅助电源装置连接至马达单元(13、32)。辅助电源装置(71)具备:辅助电源(111),为了辅助从外部电源(45)向马达单元的电力供给,而设置于供电路径;以及切换电路(114),构成为切换辅助电源相对于供电路径的连接状态。辅助电源的连接状态包含在外部电源和马达单元之间将辅助电源与外部电源串联连接的升压状态。下游侧供电线组(72)包含分支第一下游侧驱动线(161、162)和分支第二下游侧驱动线(163、164)。而且,分支第一下游侧驱动线和分支第二下游侧驱动线的各自的上游侧端部在比辅助电源靠近下游侧与供电路径连接。
