Abstract
According to one embodiment, an electric power conversion system includes a convertor, a detector, a delay controller, and a determinator. The detector is configured to detect information related to a voltage of electric power converted by the converter. The delay controller is configured to delay a conversion operation start of the converter by a first predetermined time with respect to a supply start time at which supply of the electric power is started. The determinator is configured to perform a first determination on the basis of a detection result detected by the detector before elapse of the first predetermined time from the supply start tune, and to perform a second determination on the basis of a detection result detected by the detector after the elapse of the first predetermined time from the supply start time.
