A circuit system for a railroad vehicle according to an embodiment includes a power conversion unit, a first converter, a second converter, a power storage unit, and a control unit. The power conversion unit converts power supplied from an overhead wire into power for driving a motor for running mounted on a railroad vehicle. The first converter converts power supplied from the overhead wire into DC power. The second converter converts power output from the first converter into power for driving a load mounted on the railroad vehicle. The power storage unit is electrically connected to an input side of the second converter. The control unit inputs regenerative power output from the power conversion unit to the first converter and inputs power output from the first converter to the power storage unit in a case where it is determined that the railroad vehicle is being regenerated.
