Title:
CURRENT CONTROL DEVICE, CURRENT CONTROL METHOD, AND COMPUTER PROGRAM
Document Type and Number:
WIPO Patent Application WO/2017/065055
Kind Code:
A1
Abstract:
A current control device (10) wherein a control unit (27) instructs a drive circuit (22) to switch on or off a FET (21) provided in a current path, thereby controlling the current flowing in the current path. On the basis of a detected voltage value detected by a voltage detection unit (23) and a detected current value detected by a current sensor (24), the control unit (27) estimates a resistance value in the current path subsequent to the time at which the detection is performed. In addition, the control unit (27) calculates a resistance value by dividing a voltage value associated with the detected voltage value by a current value associated with the detected current value. On the basis of the estimated resistance value and a resistance value calculated using a voltage value and a current value respectively associated with a detected voltage value and a detected current value detected again subsequent to the time at which the detection was performed, the control unit (27) determines whether to turn off the FET (21).
