Title:
POWER SUPPLY SYSTEM FOR VEHICLE
Document Type and Number:
WIPO Patent Application WO/2015/190497
Kind Code:
A1
Abstract:
In order to supply power to a battery or engine load without requiring a complicated circuit structure, the present invention is configured to be provided with thyristor switches (SCR1, SCR2) for rectifying AC power from a generator (2) and supplying said power to a battery (4) and DC loads (A, B) (5, 6), a thyristor switch (SCR3) that is disposed between the thyristor switches (SCR1, SCR2) and the generator and serves to rectify AC power from the generator and supply said power to the DC load (B), and a switch control circuit (311) that controls the conductive state of the thyristor switches (SCR1-SCR3), said switch control circuit setting the thyristor switches (SCR1, SCR2) to a conductive state and the thyristor switch (SCR3) to a non-conductive state when the terminal voltage of the battery is at or above a fixed value, and setting the thyristor switches (SCR1, SCR2) to a non-conductive state and the thyristor switch (SCR3) to a conductive state when the terminal voltage of the DC load (B) is at or below a fixed value.
