Evolutionary improvements in silicon (Si) power devices through
better device designs, processing techniques, and material quality have
led to great advancements in power systems in the last four decades.
However, many commercial power devices are now approaching the
theoretical performance limits offered by the Si material in terms of
the capability to block high voltage, provide low on-state voltage
drop, and switch at a high frequency. Therefore, in the past five to
six years, many power system designers have been looking for
alternative solutions in order to realize advanced commercial and
military hardware that requires higher power
density circuits and modules.....
