Thomas Burns Going Nowhere Without Tracing: Practical Tips for Implementing Traceability
Very often, during the implementation of a software development project, the requirement cannot be linked to the stakeholder, because important functionality is missing, or unnecessary functions appear in the final product - and all this "without tracing." That is, there is no discoverable relationship between the work relevant to that particular function and the actual need for that function. However, the concept of "traceability" is directly related to the quality of the manufactured product. Unfortunately, traceability is often overlooked.
In fact, my experience in providing consulting services shows that not a single aspect of technical requirements development is 1) so often mentioned as the most important part of the developer's activity and 2) so often ignored in practice1. I will give my guesses as to why this is happening. Then I will suggest some best practices for dealing with these causes. While traceability applies to other disciplines of the Rational Universal Process (RUP) and there are many other parameters to track, such as discrepancies, assumptions, and risks, this article focuses primarily on technical requirements.
This material is intended for those who have a general understanding of specification development and are ideally familiar with use cases.

Power electronics
Arendt Wintrich, Andrey Kolpakov Trench 4 is a versatile IGBT technology. Transition strategy
The use of new types of IGBT crystals in standard designs makes it possible to increase the technical efficiency and power characteristics of power converting devices without changing their design. The main challenge in the development of the 4th generation Trench IGBT was to comprehensively improve conductivity, dynamic performance and smoother switching behavior. The article is devoted to the features of the application of these elements, special attention is paid to issues related to the replacement of power switches of previous series with components of a new generation.

Pavel Vovk Review of new high-power LED drivers manufactured by Supertex Inc.
Over the past few years, LED lighting technologies have broken all records in the field of know-how implementation and what seemed unrealistic or, at best, unreasonably expensive, has now become the norm and quite affordable. But progress in the field of LED luminaires cannot develop only through the introduction of new technologies by LED manufacturers. This technological breakthrough must be adequately supported by the component manufacturers for LED control and power supply circuits.
