PROBLEM TO BE SOLVED: To provide a current limiting circuit with a small-scale configuration capable of inhibiting generation of arc discharge upon disconnection of DC power without reducing power efficiency during DC power supply.SOLUTION: Provided is a current limiting circuit which: stops a flow of current if the current that flows through a second contact point to a power-reception-side terminal, through which current flows during the supply of DC power via an electrode, before contact between the second contact point and the terminal is released, the second contact point being provided in a position which comes into contact with the terminal before the terminal comes into contact with a first contact point provided to the electrode for supplying the DC power when the DC power is supplied, is reduced and the terminal is in contact with the first contact point; and reduces the current flowing to the terminal through the second contact point only if the terminal is in contact with the second contact point.SELECTED DRAWING: Figure 1 【課題】直流電力供給時の電力効率を低下させずに直流電力の切断時にアーク放電の発生を小規模の構成で抑制することが可能な電流制限回路を提供する。【解決手段】直流電力の供給時に該直流電力を供給する電極に設けられる第１の接点に接触する前に、前記電極における該直流電力の供給時に電流が流れる受電側の端子が接触する位置に設けられる第２の接点と前記端子との接触が解除される前に、前記第２の接点を通じて前記端子へ流れる電流を減少させ、前記端子が前記第１の接点に接触している場合は電流を流さず、前記端子が前記第２の接点に接触している場合にのみ前記第２の接点を通じて前記端子へ流れる電流を減少させる、電流制限回路が提供される。【選択図】図１
