Title:
VEHICLE POWER SUPPLY SYSTEM
Document Type and Number:
Japanese Patent JP2016005298
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To supply power to a battery and an engine load without a complicated circuit configuration.SOLUTION: A vehicle power supply system includes: thyristor switches (SCR1, SCR2) for rectifying AC power from a generator (2) to supply to a battery (4) and DC loads A, B (5, 6); a thyristor switch (SCR3), disposed between the thyristor switch and the generator, for rectifying the AC power from the generator to supply to the DC load B; and a switch control circuit (311) for controlling the conduction state of the thyristor switches (SCR1-SCR3). When the terminal voltage of the battery is a constant value or greater, the switch control circuit sets the thyristor switch (SCR1) to a conduction state, and the thyristor switch (SCR3) to a non-conduction state. Also, when the terminal voltage of the DC load B is a constant value or smaller, the switch control circuit sets the thyristor switches (SCR1, SCR2) to the non-conduction state, and the thyristor switch (SCR3) to the conduction state.
