Abstract
A power source system may include a main power source, a power converter including a capacitor, a relay configured to switch between connection and disconnection between the power converter and the main power source, an auxiliary power source, a boost converter having a low voltage terminal thereof connected to the auxiliary power source, and having a high voltage terminal thereof connected to the power converter without interposing the relay, and a controller configured to pre-charge the capacitor prior to placing the relay in a connected state. During the pre-charging of the capacitor, the controller may be configured to set an output current of the boost converter to a first current value while a specific auxiliary device connected to the auxiliary power source executes a specific process, and change the output current to a second current value larger than the first current value after the execution is completed.
