Step up and step down controller, particularly for feeding, for use with half bridge and full bridge for converting direct current voltage into output direct current voltage, has fuel cells in electrical network

摘要

The step up and step down controller (1) has fuel cells (10) in an electrical network. A controlling unit is provided for clocked controlling of two switching elements (24,34). A step up and step down controlling unit (2,3) has a half bridge (5,6) for the assumption of the technical switching function of series connection made of free-wheeling diode and switching elements.
