Abstract
A control apparatus includes: an operation prediction section that predicts that equipment will shift from an operation stopped state to an operating state; and a supply control section that, if it is not predicted that the equipment will shift from the operation stopped state to the operating state, sets a main-electrical power conversion device to the operation stopped state and operates an auxiliary-electrical power conversion device to supply electrical power from the auxiliary-electrical power conversion device to the equipment, and that, if it is predicted that the equipment will shift from the operation stopped state to the operating state, operates the main-electrical power conversion device to supply power from the main-electrical power conversion device to the equipment. Power conversion efficiency of the auxiliary-electrical power conversion device is higher than that of the main-electrical power conversion device within a load current range corresponding to a dark current flowing through the equipment.
