Improving Short-Circuit Withstand Time in GaN HEMT Power Devices
By Sonu Daryanani
The adoption of wide-bandgap (WBG) power devices in industrial motor drive power conversion can significantly improve system efficiency and power density and provide other advantages, such as less audible noise and more precise control from faster switching. Lower conversion losses in these applications are a key part of achieving the net-zero carbon footprint to combat climate change, as motor drives account for 60% of total electricity usage. In this article, we will discuss a key parameter, the short-circuit withstand time (SCWT), in gallium nitride (GaN) HEMT power devices. This article is a summary of a presentation by Davide Bisi and co-workers from Transphorm, as well as Yaskawa Electric, at the APEC 2024 conference.

Crafting a Comprehensive Quality Control Plan With Burn-In Tests
By Emily Newton
A burn-in test involves exposing a component to high temperatures and voltage levels. This type of semiconductor production testing allows engineers, manufacturers and other relevant professionals to drastically shorten the time before defects appear and potentially compromise reliability. How should burn-in tests fit into an overall quality control plan? Here’s what company officials should know when implementing this process.
14-28V to 12V-3.5A 1MHz DC to DC Step-Down Converter
By Hesam Moshiri
A DC-to-DC converter is one of the most commonly used circuits in electronics, especially in power supply applications. Three main types of non-isolated DC-to-DC converters are Buck, Boost, and Buck-Boost. Sometimes a buck converter is also called a step-down converter and a boost converter is also called a step-up converter. A buck converter reduces (steps down) the input voltage while increasing the output current.
Towards Sustainable Electric Mobility: Addressing Carbon Emissions Across the Value Chain
By Giovanni Di Maria
Today’s electric vehicles, directly or indirectly, cause greenhouse gas emissions during their life cycle. Emissions do not only refer to the operational phases of the means of transport but are also closely linked to the production of the vehicle itself, the extraction and processing of raw materials, the assembly and transport operations, and the possible source of the energy for charging from non-renewable sources and for disposal at the end of its life. The reduction of the carbon footprint, in the management of electric vehicles, is therefore not an operation linked to a single branch, but it embraces various sectoral decisions.
