To provide a power conversion system capable of starting the power converter in the event of a power failure of an electric power system.SOLUTION: A power conversion system 100 includes a power converter 1 and a cable support device 2. The power converter 1 is capable of adjusting DC power which is discharged from a storage battery 31 of a moving body 3. The cable support device 2 supports a cable C1. The cable C1 forms a power supply path between a storage battery 31 and a power converter 1. The power converter 1 has a main circuit 121 that adjusts DC power, and a control circuit 122 that controls the operation of the main circuit 121. The power conversion system 100 further includes an auxiliary power supply unit 24. The auxiliary power supply unit 24 is configured so as to, when the electric power system 4 loses power, supply a control power for activating the control circuit 122 from the cable support device 2 to the power converter 1.SELECTED DRAWING: Figure 1
【課題】電力系統の停電時において、電力変換器を起動可能にすること。【解決手段】電力変換システム100は、電力変換器1と、ケーブル支持器2と、を備える。電力変換器1は、移動体3の蓄電池31から放電される直流電力を調整可能である。ケーブル支持器2は、ケーブルC1を支持する。ケーブルC1は、蓄電池31と電力変換器1との間の電力供給路を形成する。電力変換器1は、直流電力を調整する主回路121と、主回路121の動作を制御する制御回路122と、を有する。電力変換システム100は、補助電源部24を更に備える。補助電源部24は、電力系統4が停電した際に、制御回路122を起動させるための制御電力を、ケーブル支持器2から電力変換器1へ供給する。【選択図】図1
