Title:
直接酸化型燃料電池電源とともに使用するためのスイッチングDC-DC電力コンバータおよびバッテリ充電器
Document Type and Number:
Japanese Patent JP2006501798
Kind Code:
A
Abstract:
This invention presents a method and apparatus for controlling the operating point, i.e. the output voltage or current, of a fuel cell to a desired value, efficiently transferring the available fuel cell power to a rechargeable battery and load, and isolating the fuel cell from the battery and load. Active control of the operating point of the fuel cell allows for optimized power output and fuel cell efficiency. This invention uses feedback from the input to regulate the input voltage or current. The output of the DC-DC converter either charges the battery or helps the battery supply the load, and is maintained equal to the battery voltage as the output of the DC-DC converter is directly connected to the battery.
