Part 1Evolving Power for Electronic Systems: power architectures, dc-dc converters, ac-dc power supplies, and digital power conversion

Changing conditions in the markets for ac-dc power supplies and dc-dc converters will be reviewed. For the first time, markets for ac-dc power supplies will experience faster growth than dc-dc converters. The faster growth in ac-dc power is being fueled by new applications. Applications for traditional voltage-regulated ac-dc power supplies will shrink while emerging markets for current-regulated ac-dc power supplies will become the new growth engines for this segment. In the case of dc-dc converters, today’s Intermediate Bus Architecture (IBA) is being replaced by the new Centralized Control Architecture (CCA). The CCA will consume relatively more embedded dc-dc converters and fewer dc-dc converter modules compared with the IBA, reducing the growth potential for this segment. For ac-dc power supplies and dc-dc converters, the adoption of digital power technologies, new semiconductor devices and new packaging options will provide significant opportunities for product differentiation.

Part 2Expanding Markets for Alternative Energy Technologies: milliWatt energy harvesting and thin-film batteries, MegaWatt photovoltaics and wind energy 

Improvements in the cost/performance of small-scale (milliWatt) energy harvesting technologies and large-scale (MegaWatt) energy harvesting technologies are driving growth for both of these segments. There has been a convergence occurring between the power needs of sensor nodes in building automation applications and the power generation capabilities of energy harvesting devices. As a result, in large-scale building automation applications, energy harvesting (also called energy scavenging) and thin-film battery storage are more cost-effective compared with many battery-powered solutions. Similar improvements are occurring in large-scale (MegaWatt) photovoltaic and wind power systems. In addition to improvements in the underlying technologies, developments such as the growing use of building-integrated photovoltaic and wind systems plus improved system architectures are fueling market growth. Expansion in these applications is leading to growing demand for inverters.

Part 3Emerging Opportunities for Power Conversion: vehicle electrification, dc power distribution in buildings, and alternative manufacturing locations

New, high-volume applications are emerging for ac-dc power supplies, dc-dc converters, and inverters in both vehicle electrification and building powering. Opportunities in vehicles extend far beyond automobiles and include trucks, buses, off-road (utility), construction, and specialty vehicles. Also, in non-automotive vehicles, various “auxiliary” power applications can be even larger than the drive-train opportunities for power converters. Another emerging opportunity is the use of both high-voltage and low-voltage dc power distribution in buildings. A convergence of technologies is occurring that will change how buildings are powered. These technologies include the continued rapid growth of distributed generation resources (photovoltaic panels, wind turbines, fuel cells, micro turbines, etc.); the emergence of high-efficiency lighting technologies (especially solid-state LED lighting); wireless building automation systems; demand-side management of building energy use by electric utilities; and more. Finally, an “African Safari” will show how certain locations in Northern Africa are becoming manufacturing hubs for servicing European markets.
