Dear Friends,

Today the early bird discount for my WBG event ends, so you better be quick and save some money! The program is developing fantastically, and we are still getting requests from companies to join us. I'm afraid the time will soon come when we'll have to close it, as we want to find the right mix between contributions and time for networking in Munich! Go to bodoswbg.com and check out the program. More and more titles and abstracts are coming in these days, so you will be able to identify the presentations that are relevant to you and plan your day in advance. I am very much looking forward to the event, truly one of my highlights of the 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. We all share one world.
As a publisher I serve the world: one magazine, on time, every time.

Best Regards,

Bodo Arlt editor@bodospower.com

Cover Story
Pushing Module Power Density to the Limit: Innovative Technologies for 1700V and 3300V SiC Delivering Super Power Density

Full Silicon Carbide (SiC) MOSFET modules have clear performance benefits, especially where high power density is required, but how to achieve the highest possible power density? Hitachi consistently breaks new ground bringing innovation and improvements to address future market requirements and push the limits of what's possible. This article discusses selected topic of fast switching 1700V and 3300V Full SiC MOSFET power modules. Some key technology milestones are presented and their impact on performance demonstrated through simulation results based on extensive lab measurements. The results underline the module performance and show the wide application possibilities for high performance SiC power modules.

Wide Bandgap
GaN Transistors Simplify the Design of High Current Motor Drive Inverters

Battery-powered industrial vehicles such as forklifts, manual handlers, or warehouse automatic vehicles require high-current inverters to drive the electric motors. Gallium nitride technology helps to increase the power capability and simplify the inverter design in these applications.
By Marco Palma, Director, Motor Drives Systems and Applications, Efficient Power Conversion (EPC)

IGBTs
Superior Solution for Wind Converter Designs

One of the major challenges of the 21th century is to contain global warming in order to limit the consequences of climate change. This target will only be reached by dramatically reducing the emission of greenhouse gases during the first half of the century. For a perspective, in 2019 alone, energy and heat production were the biggest single contributor to the greenhouse effect with nearly one third of the global emissions worldwide.
By Marcel Morisse, Field Application Engineer, and Michael Busshardt, Senior Technical Marketing Manager, Infineon Technologies

Wide Bandgap
Bringing Reliability to SiC Power Modules

Harnessing the unique electrical advantages of wide-bandgap silicon carbide (SiC) in commercial applications requires addressing reliability challenges caused by the material's mechanical properties. With its advanced die-attach technology, Vincotech is leading the way.

Thermal Management
Estimating Virtual Temperature Using Dynamic Thermal Impedance Curves for a Semiconductor Diode

In applications like switched-mode power supplies, semiconductor devices often run in pulsed mode, not continuous waves. These devices might never reach a stable operating point, making steady-state thermal resistance unsuitable for accurate thermal modeling. This article introduces an alternative approach: dynamic thermal impedance curves for modeling device behavior. This technique is exemplified through successful SPICE simulations on a practical diode.

Packaging
Improved TO-247PLUS Discrete Package Solution for High Power Applications

High power applications demand high power density and reliable power semiconductors at a reasonable cost. Discrete devices lower the total cost of the solution, but have to withstand high thermal requirements during heavy load cycles. To support such requirements, power semiconductors should have low overall losses, use the largest chips available in a standard package, and have a good cooling system.

Motion Control
How to Achieve Precise Motion Control in Industrial Drives

When riding in an elevator, I'm sure you expect a smooth and safe ride from one floor to the next. In an elevator drive, precise motion control enables the elevator to stop at specified positions and to slow down to a full stop smoothly. A lack of precise motion control could result in the elevator stopping at misaligned positions versus building floors, causing those inside to feel dizzy or unsafe.

Power Supply
Instrumentation Power Supply Basics

Power supply test instruments are no longer just DC output devices. Like the products they work with, power supplies have evolved to interface with PCs, simulate power sources such as batteries and solar cells, and execute test sequences. Individual instruments can range in power from as low as 30 W to as high as 60 kW with voltages as high as 2000 V, and current output as high as 1000 A. Power supplies are sophisticated instruments. This article will start with the basics and review some of the features of today's power supplies.

Battery
A Guide to Battery Fast Charging - Part 1

While higher battery capacity increases a device's operating life, keeping charging time down presents additional challenges for designers. Fast charging applies to a wide range of devices, including consumer, medical, and industrial applications. This two-part series provides an overview of the challenges associated with implementing battery fast charging capabilities. Part 1 discusses partitioning of the charger and fuel gauge between the host and battery pack to increase system flexibility, minimize power dissipation, and improve the overall user experience. It also covers monitoring functions that ensure safe charging and discharging. Part 2 will explore the implementation of a fast charging system with parallel batteries.
