Silicon Carbide Devices in SMPC Applications

Silicon diodes used as output rectifiers in SMPC circuits also contribute to power loss. As the diodes switch between the forward- and reverse-biased states, a 

Silicon Carbide Technology and Power Electronics Applications 

Until recently, most reported evaluations and analyses of SiC components, as they relate to circuit performance, have been limited to p-/-n and Schottky diodes. This has been due to both the complexity of the analyses and availability of stable components. In the previous discussions, it was noted that a variety of techniques have been employed to expand the operating regime of Si-based switching converters by ameliorating the electrical stress. The introduction of commercially available SiC semiconductor components by Infineon and Cree have raised the question of how SiC technology will impact the next generation of switching power circuits.
