Low-Inductance DC Power Bus

Anew generation of power electronic conversion systems is being enabled by wide-bandgap (WBG) devices. Applications in civilian and defense sectors are already realizing improved power density and efficiency in power converters that utilize silicon carbide (SiC) and/or gallium nitride (GaN) switches; however, as semiconductor switches become capable of greater hold-off voltage, higher switching frequency, and higher junction temperature, limits on converter performance will depend on the remainder of the system: device packaging, filter components, and thermal management, as examples.
