Title:
POWER SUPPLY SYSTEM
Document Type and Number:
Japanese Patent JP2016019398
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To appropriately correct a power allocation among plural DC power supplies so as to eliminate a power deviation caused by a sensor property and the like in a power supply system that includes the plural DC power supplies.SOLUTION: A power supply system includes: a load; a power line connected to the load; first and second DC power supplies capable of supplying the load with power; a power converter connected to at least one of the first and second DC power supplies and the power line; and a control device for controlling operations of the power converter. In the system, the first and second DC power supplies are parallel to the power line; and the first DC power supply functions for controlling a voltage, while the second DC power supply functions for controlling power. Further, the control device sets a difference between required power of the load and target output power of the first DC power supply as target output power of the second DC power supply, and corrects the target output power of the first DC power supply on the basis of a difference between actual output power of the second DC power supply and the target output power of the second DC power supply (S22).SELECTED DRAWING: Figure 18
