保護装置
Document Type and Number:
Japanese Patent JP7246010
Kind Code:
B2
Abstract:
A protection device (30) connected to a DC power supply device (50) for outputting DC power to a DC electric circuit (12), the protection device (30) being provided with: a first conductor (31) connected to the high-potential-side output terminal (51) of the DC power supply device (50); a second conductor (32) connected to the low-potential-side output terminal (52) of the DC power supply device (50); a diode (34) having a cathode connected to the first conductor (31) and an anode connected to the second conductor (32); a current sensor (46) connected in series to the diode (34), the current sensor (46) measuring the current flowing between the first conductor (31) and the second conductor (32); a switch (36) connected in parallel to the diode (34); and a controller (38) for controlling the state of the switch (36). The switch (36) is controlled on the basis of the current value (Id) measured by the current sensor (46).
