Preventing global warming has made carbon dioxide (CO2 ) emissions reduction a strong focus worldwide. Emissions reduction, in combination with reducing fossil-fuel use as an energy source, has led to several disruptive behaviors in applications we use every day. The trend is now toward energy-efficient, robust and compact systems. Economically, this also translates into energy savings for consumers.
For example, automakers have committed to developing and selling hybrid electric vehicles/ electric vehicles (HEVs/EVs), which are expected to reach 8 million units by 2021 . Industrial high-power products such as motor drives, solar inverters and servers for data centers are also moving toward achieving higher system efficiency, longer lifetimes and more compact solutions to realize carbon-reduction goals.
