Title:
POWER SOURCE DEVICE, VEHICLE, AND SWITCHING CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/195060
Kind Code:
A1
Abstract:
Provided is a power source device making it possible to reduce a leakage current caused by connecting to a single-phase power source. A power source device (1) is provided with: first through fourth terminals (101A, 101B, 101C, 102); a first load section (103A) provided to first and fourth power lines (A1, A2); a second load section (103B) provided to second and fifth power lines (B1, B2); a third load section (103C) provided to third and sixth power lines (C1, C2); a plurality of capacitor sections (A3, B3, C3, A4, B4, C4) provided between first through sixth power lines (A1, B1, C1, A2, B2, C2) and ground (G); and a switch unit (105-106) for switching at least one power line (B2, C2) out of the fourth through sixth power lines to being conductive or being non-conductive. The switch unit (105-106) makes the power line (B2, C2) non-conductive if a single-phase power source (20) has been connected to the first and fourth terminals (101A, 102).
