POWER FEEDING CONTROL DEVICE

To provide a power feeding control device capable of setting a potential difference between ground voltages of a plurality of communication devices communicating with each other to a value within a desired range.SOLUTION: Provided is a power feeding control device that comprises a first control device that controls a power reception current drawn by a power supply circuit included in a power reception device. The power reception device comprises a second control device that controls the power supply circuit and can communicate information with communication devices via a first cable. The power supply circuit receives a power feeding current from a power supplying circuit. The first control device determines whether or not a potential difference is generated between a ground voltage of each communication device and a ground voltage of the power reception device, and if it is determined that the potential difference is generated, makes the second control device control the power supply circuit so that the power supply circuit draws a second current smaller than a first current that is the maximum current which can be supplied as the power feeding current.SELECTED DRAWING: Figure 1 【課題】互いに通信を行う複数の通信装置の、グランド電圧同士の間の電位差を所望の範囲内の値に設定することができる給電制御装置を提供する。【解決手段】本開示に係る給電制御装置は、受電装置が備える電源回路が引き込む受電電流を制御する第１制御装置を備え、受電装置は、電源回路を制御する第２制御装置を備え、第１ケーブルを介して通信装置との情報通信が可能であり、電源回路は、電源供給回路から給電電流が入力され、第１制御装置は、通信装置のグランド電圧と、受電装置のグランド電圧との間に電位差が生じているか否かを判定し、電位差が生じていると判定した場合には、電源回路が、給電電流として供給可能な最大の電流である第１電流よりも小さい第２電流を引き込むように、第２制御装置に電源回路を制御させる。【選択図】図１
