Requirements for MOSFETs in Fuel Cell Power Conditioning Applications

Fuel cell power conditioning systems consist of one or several voltage converters as well as energy storage devices. For generation of required voltages and controlled energy transfer appropriate converter topologies are necessary. Low-voltage power MOSFETs often can be used as switching devices for such converters. Possible ways of utilisation of low-voltage MOSFETs in different topologies and the resulting requirements are discussed.
