|Dramatic changes in the power semiconductor space are enabling and enhancing the power conversion technologies in applications such as computing, consumer products, and telecommunications. Many emerging applications have power technologies at their core and these applications are extensively technology driven. Key component areas (e.g. magnetics, capacitors, semiconductors, and packaging) are addressed from the perspective of how they impact the growth of the power conversion technologies.
This chapter, which was developed in conjunction with the Power Supply Manufacturers Association (PSMA), discusses dominant power conversion trends and challenges, and metrics in their respective end segments, providing a comprehensive view of power conversion needs. A combined qualitative and quantitative picture is presented of key technologies and trends in the four representative power converter technologies (AC-DC front-end power supplies, AC-DC external power supplies, isolated DC-DC power supplies and non-isolated DC-DC power supplies). Attribute tables provide a quantitative indication of the mega-trends in each area.
