Abstract
A power source apparatus of a car is provided with contactors () connected to an output-side of a battery (); a pre-charge circuit () made up of a series connected pre-charge resistor () and a pre-charge relay (), which is connected with a contactor () to supply auxiliary charge to a capacitor () connected to a car-side of the battery (); and a control circuit () to control the contactors () and the pre-charge relay (). The pre-charge resistor () is connected in parallel with a contactor (), and the pre-charge relay () is connected in series with that contactor (). The control circuit () switches the pre-charge relay () ON to pre-charge the car-side capacitor (), and then switches the contactor () ON to connect the battery () to the car-side.
