ON-VEHICLE POWER SUPPLY APPARATUS AND CONTROL METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To limit an output current.SOLUTION: The on-vehicle power supply apparatus includes: a voltage conversion section for voltage-converting an input voltage; a first control section for controlling a voltage conversion operation of the voltage conversion section to obtain an output voltage value based on an output voltage preset value; and a second control section for variably controlling the output voltage preset value so that an input current value in the voltage conversion section approaches an input current limit value instructed by an on-vehicle side control section.
