This article discusses the challenges that thermal management raises due to increase power density, especially with chip-scale packaging (CSP). What is sometimes overlooked, however, is that CSP eGaN® power FETs and integrated circuits have excellent thermal performance when mounted on standard printed circuit board (PCBs) with simple methods for attaching heat sinks. Simulations, supported by experimental verification, examine the effect of various parameters and heat flow paths to provide guidance on designing for performance versus cost.

Gallium nitride (GaN) transistors have been in mass production for over 10 years. In their first few years of availability, the fast switching speed of the new devices – up to 10 times faster than the venerable Si MOSFET – was the main reason for designers to use GaN FETs. As the pricing of GaN devices normalized with the MOSFET, coupled with the expansion of a broad range of devices with different voltage ratings and power handling capabilities, much wider acceptance was realized in mainstream applications such as DC-DC converters for computers, motor drives for robots, and e-mobility bikes and scooters. The experience gained from the early adopters has led the way for later entrants into the GaN world get into production faster. This article is the first in a series of articles discussing three topics that can help power systems designers achieve the most out of their GaN-based designs at the lowest cost. The three topics are: (1) layout considerations; (2) thermal design for maximum power handling; and, (3) EMI reduction techniques for lowest cost.

The Trilogy of Wireless Power Transfer consists of three parts: Basics Principles of Wireless Power Transmission, Wireless Power Transfer Systems and Applications. The first part of the book explains the basic physical principles and the different methods of contactless power transmission. Furthermore, the leading standards are presented in this part. The second part describes wireless power transfer systems, the different topologies of wireless power transmission, the right selection of transmitter and receiver coils required to increase efficiency, and the selection of transistors, for instance. The third part is dedicated to practical applications. This includes applications within the scope of the Qi standard, as well as examples of proprietary solutions. An overview of EMI-relevant topics for closely and loosely coupled systems, as well as an example of a multimode wireless power transmission system round out the practical part. The authors of the "Trilogy of Wireless Power Transfer" are Cem Som, Division Manager Wireless Power Transfer at Würth Elektronik eiSos; and Dr. Michael de Rooij, Vice President Applications Engineering at Efficient Power Conversion Corporation, Inc. The book costs 19 euros and can be ordered from Würth Elektronik eiSos or through bookstores.

As GaN-on-Si becomes more common in DC-DC converter designs, questions often arise from experienced designers about the impact of the unique characteristics of GaN transistors when used as synchronous rectifiers (SRs). In particular, the third quadrant off-state characteristics, better known as “body diode” conduction in Si MOSFETs, which is activated during converter dead-time, is of interest. For this article, the focus will be on the similarities and differences of Si MOSFETs and eGaN^® FETs when operated as a “body diode” and outline their relative advantages and disadvantages.

Best design practices utilize the advantages offered by eGaN FETs, including printed circuit board (PCB) layout and thermal management. As GaN transistor switching charges continue to decrease, system parasitics must also be reduced to achieve maximum switching speeds and minimize parasitic ringing typical of power converters.

Power transistors with faster switching speeds will enable power supplies with smaller form factors and higher energy transfer efficiencies. Indeed, the elimination of heat sinks will give designers the ability to visualize entirely new form factors for power bricks and modules, including those enabling wireless power transfers. Gallium-nitride (GaN) transistors fabricated on silicon substrates can boost efficiencies and help shrink the footprint of power supplies.
