In 2018, 1.1 billion people still lacked access to energy services. Most of these people are located in remote areas which are hard to reach, especially with conventional methods of grid extension. Even if the number of people without energy access is decreasing and the number of people gaining access to electricity through renewable sources is...

To this day, 16% of the world’s population still has little or no access to electricity. The majority of which is located in rural regions of developing countries, such as India and most countries in sub-Saharan Africa. As a part of the Sustainable Energy for All (SE4All) initiative, a multi-tier framework that aims to categorize and quantify...

Converters are the essential devices in the energy transformation process from the wind generators to the grid. Power electronic semiconductors have a high share of failures in the power electronic converters. Therefore, the reliability based on lifetime of power semiconductor generates more and more attention. This thesis presents a comparison...

The war of the currents started in the late 1880s and early 1890s between the main players being: the direct current (DC)–based Edison Electric Light Company and the alternating current (AC)–based Westinghouse Electric Company. AC came out as the winner because of the need to increase voltage with AC transformers for long-distance power...

The transportation industry is causing 14% of the worldwide greenhouse gas emission. Therefore, the United Nation concluded with the Paris climate agreement to reduce and limit their emissions to keep the global average temperature increase below 2 degrees Celsius. Based on the agreement the European union introduced new regulations to limit the...

Power switches are used very often in applications such as industrial and automotive. The main function of these devices is to switch the energy delivered to the load so that power could be transferred in the most optimum way meeting a certain set of requirements. Due to recent and continuous developments in system-on-chip technologies, it will...

The fact that the developing world struggles to cover even the most basics of needs, in contrast to the developed world, is tangibly connected to the lack of electricity. As many developing nations, especially the ones located in rural areas, face many difficulties to access the grid, alternative stand-alone solutions such as Solar Home Systems ...

Nowadays there is a movement towards the creation of HVDC grids. The massive integration of renewable energy sources, the operation of the current grid close to its limits and the need to facilitate the power trade are some of the reasons driving the research on HVDC grids. Towards HVDC grids, there are still some obstacles and technical...

It is expected that DC grids will evolve into large meshed networks, which will have multiple DC voltage levels. Two DC grids operating at different voltage levels could be interconnected using a DC-DC converter. The role of the DC-DC converter in meshed DC networks is similar to the role of a transformer in traditional AC systems. The DC-DC...
