Dear Friends,

My recent WBG Event in Munich was a great success. A huge thank you to everyone who joined us! The roundtable on the first day was everything I had hoped for-a lively discussion among the experts on stage. Authentic, in-depth conversations don't need a script. Bringing together engineers of this caliber is a unique opportunity, and it's best not to restrict them with overly narrow topics.

The second day was equally informative. In total, 40 presentations provided the most comprehensive update on WBG you could ask for. I truly appreciate the enthusiasm and dedication of our speakers-you made the event the success it was.

A big thank you also goes to our sponsors and exhibitors, who made it all possible. Events like these simply can't happen without great partners. Thank you all!

Holger is already in contact with the Hilton, and things are looking good for our return in early December 2025. Keep an eye out for announcements throughout next year.

For now, I wish you all a Merry Christmas and a Happy New Year!

Find all magazines from 2006 on in the free archive on my website. Do not miss our Chinese version bodospowerchina.com. There is no better way to communicate. As a publisher I serve the world: one magazine, on time, every time.

Merry Christmas,

"A much better Way to conduct Heat away from the Die" – especially in GaN Applications
QPT has just filed a patent for a way to attach dies to the heat spreaders or substrates which are typically Aluminium Nitride (AlN), which it calls qAttach™. This is said to provide "a much better way to conduct heat away from the die and also increases reliability" as the assembly process places less stress on the substrates, which is one of the biggest challenges the high-power semiconductor packaging industry faces.

Design and Simulation
In Pursuit of Cool: Building Better Thermal Models with Cauer and Foster Chains

When designing and analyzing power electronic circuits in simulation tools, ensuring that such systems are kept sufficiently cool requires accurate thermal models. Engineers widely use lumped-element thermal models such as Foster and Cauer chains to predict device temperatures and heat flow. While these chains look simple, they have subtle complexities that can undermine model accuracy and thermal behavior. Here, we dive into how to get the most out of these models – from measuring impedance curves to best practices for building better, more reliable thermal models.

Power Modules
The Power Module that Stabilizes the Grid

In modern power grid systems, maintaining a stable grid frequency is more important than ever due to new challenges, such as the transition to renewable energies. This is largely due to the significant amount of energy consumed in today's world and governmental goals to reduce carbon emissions. Consequently, the demand for energy storage devices is growing. A crucial element of an effective Energy Storage System (ESS) is the Power Conversion System (PCS). The PCS acts as an interface between the direct current (DC) batteries and the electrical grid.

DC/DC Converter
Kilowatt DC/DC Converters for Fuel Cell Solutions

Fuel cells are electrochemical devices that convert the chemical energy from a gaseous fuel, often hydrogen, directly into electrical energy. This process occurs in a reaction chamber, or "cell". When hydrogen serves as the fuel, the process resembles electrolysis in reverse.

MOSFETs
Driving a High-Side MOSFET Input Switch Using Active Low Output for System Power Cycling

Applications such as wireless transceivers where systems are placed in remote areas and usually powered with a battery require continuous operation since they are rarely visited and intervened. A system reset is required after persistent inactivity or a system hang-up to restore operation. This can be achieved by cutting off the supply voltage, disconnecting it from the system, and connecting it again to initiate a restart. This article discusses methods and techniques for using the active low output of a supervisory circuit to drive a high-side input switch to execute a system power cycle.
