Title:
POWER SUPPLY DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/157962
Kind Code:
A1
Abstract:
This power supply device (1) is provided with: relays (Ry1, Ry2) that are provided between input/output connection terminals (IO1, IO2), to which a storage battery (B1) is connected, and a DC-DC converter (10); a relay (Ry3) that is connected in parallel to relay (Ry1); and a control circuit (12). The relays (Ry1, Ry2, Ry3) are off in an initial state. The control circuit (12) turns relay (Ry1) off and relays (Ry2, Ry3) on at a prescribed timing. When the output voltage of the DC-DC converter (10) is at or above a prescribed value, the control circuit (12) turns relays (Ry1, Ry2) on and relay (Ry3) off. This makes it possible to provide a power supply device in which the impact of reverse connection of a DC power source is prevented.
