Title:
直流電源極性反転装置及び配線用遮断器
Document Type and Number:
Japanese Patent JP6732606
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a DC power supply polarity inversion device capable of preventing a secondary-side circuit from being damaged even when a DC power supply device is connected in reverse polarity.SOLUTION: A DC power supply polarity inversion device includes: an input part 41 which is connected to a DC power supply device 1 and receives the power supply feed; an output part 42 for feeding a power supply of the DC power supply device 1 to a secondary-side circuit; a polarity determination circuit 43 for determining the polarity of the DC power supply device 1; a polarity switching circuit 44 for inverting the polarity when it is determined that the polarity determination circuit 43 has the reverse polarity; and an output delay circuit 45 for stopping output to the secondary-side circuit until time to reverse the polarity by at least the polarity switching circuit 44 after start of the power supply feed from the DC power supply device 1 and performing output to the secondary-side circuit after time is exceeded.SELECTED DRAWING: Figure 1
