Abstract
A charging system for a vehicle includes: a power transmitter transmitting power for charging a battery of a vehicle; a charger including a three-phase motor and inverter, and receiving the power from the power transmitter; an input voltage calculating processor selecting any one of a plurality of predetermined duty ratios and calculating a value of an input voltage supplied to the charger based on the selected duty ratio and a voltage value of the battery of the vehicle; an input current calculating processor calculating a value of an input current based on the calculated value of the input voltage and a value of the power transmitted by the power transmitter; a power transmission controller instructing the calculated input current to be input to the charger; and a charging controller instructing the battery of the vehicle to be charged.
