Opis:
Is the world’s power engineering at a crossroads? Will ongoing climate changes and rise of new technologies such as the Internet of Things (IoT), Smart City or e-mobility give us a completely different perspective on the world’s future energy? What are our actual visions and development forecasts in this matter? Who is right concerning this matter, large energy companies and some politicians, environmentalists, climate researchers and all kinds of visionaries? Is transformation based on solar energy and hydrogen a holy grail for the energy sector? The author of this article tries to find answers to these and many other questions. Today we can already accept as a proven thesis that rapid and dangerous climate changes for our civilisation can also be attributed to high carbon and low-efficient power engineering. Power engineering and climate neutrality are no longer just problems for politicians, companies, and scientists, but have become a challenge for our civilisation. If we are to save the Earth, our civilisation has to change its mentality and develop ideas that will not prioritise economic growth and high consumption but sustainable growth in harmony with nature. For this to happen, the way people think about energy and global transformation must also change. The foregoing general remarks, but also the fact that a gradual transition from traditional large-scale fossil fuel-based energy generation to distributed energy generation based on renewable resources is inevitable, constitute the main message of this article. The article also aims to discuss the role of the Institute of Fluid-Flow Machinery of the Polish Academy of Sciences (IMP PAN) in Gdańsk in the process of energy transformation in our country. The institute, as the coordinating entity of over a dozen of high-budgeted national and European projects in the field of environmentally-friendly power engineering, has contributed to some extent to the creation of conditions required for the development of prosumer power engineering (or more broadly: civic power engineering) in our country.

Opis:
This paper presents examples of technologies for distributed energy generation developed under the projects coordinated by the IFFM PAS in Gdańsk. These are CHP units (generating heat and electricity) for houses with a power from several to tens of kW and for municipalities in the form of the Municipal Energy Centers (with a capacity of several hundred kW up to several MW). A unique project, specializing in “energy-plus” technologies for residential houses and other buildings, which aims to build a Research Centre of PAS in Jabłonna is also presented,. These are key technologies for energy sector with respect to distributed generation. Additionally, the article discusses the conditions and opportunities for the development of energy generation or more broadly: civic energy generation in our country. Civic energy generation is a great vision in which the citizen becomes an entity and do not subject to the energy market, and additionally has its virtual advisor in the form of smart grid and data processing technologies in a “digital cloud”.

Opis:
The main drawback of any Design for Reliability methodology is lack of easy accessible reliability models, prepared individually for each critical component. In this paper, a reliability model for SiC power MOSFET in SOT – 227 B housing, subjected to power cycling, is presented. Discussion covers preparation of Accelerated Lifetime Test required to develop such reliability model, analysis of semiconductor degradation progress, samples post-failure analysis and identification of reliability model parameters. Such model may be further used for failure prognostics or useful lifetime estimation of High Performance Power Supplies.
