OUT OF E-MOBILITY Design Trends for

Efficient Power

Delivery

Wireless-power–transfer capabilities have been widespread in commercial, industrial and
automotive applications over the past decade. Battery-powered items demanding high-power

charging are trending. Companies have created many highly integrated wireless charging ICs to suit
these severe system and regulatory requirements for higher-power wireless charging. In this issue,
Infineon Technologies principal applications engineer Nicholaus Smith and senior staff systems
engineer Hariom Agrawal discuss a typical wireless power system and how to design it for optimal
thermal management. Ever since wide-bandgap materials have been incorporated into various
manufacturing technologies, it has been possible to achieve high efficiency in various power systems.
Although there have been several developments in SiC and GaN devices, the optimization of such

devices for electrical conductivity remains a major setback. In this issue, we will analyze different
aspects about wide-bandgap semiconductor devices for high-voltage applications. Other topics
include AC/DC converters for fast-charging stations, vertical GaN, PoE-powered devices, electric
power steering (EPS), SiC power module packaging solutions for medium-voltage grid applications
