Title:
ELECTRIC POWER SUPPLY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2013/088798
Kind Code:
A1
Abstract:
First to third power conversion devices are connected to an interconnected feed line in the order of, from upstream, the first power conversion device, the second power conversion device, and the third power conversion device. A first detector is provided between the first power conversion device which is connected to a solar cell and the second power conversion device which is connected to a storage cell, and detects a reverse power flow on the interconnected feed line. A second detector is provided between the second power conversion device and the third power conversion device which is connected to a fuel cell, and detects the reverse power flow on the interconnected feed line. The second power conversion device operates so that the reverse power flow detected by the first detector becomes zero, and the third power conversion device operates so that the reverse power flow detected by second detector becomes zero.
