Special Issue Information

Dear Colleagues,

The pursuit of miniaturization of power electronic devices requires increasing the frequency of their operation. The increase in this frequency is limited by the dynamic properties of the elements contained in such devices, i.e., semiconductor and magnetic elements, which narrows the scope of their application and affects the energy efficiency of power electronic systems. For example, an increase in the operating frequency of electronic devices containing magnetic elements causes decrease of energy efficiency of the considered system. The reason for the reduced efficiency is an increase in power losses in magnetic elements. Additionally, an increase in the operating frequency causes an increase in the temperature of the considered elements as a result of thermal phenomena occurring in them, such as self-heating or mutual thermal coupling between the components of the mentioned element (core, winding). Therefore, the aim of this issue is to identify new trends and research in the field of modern electronic components used in power systems and to present the influence of selected properties of electronic components of the considered systems. Additionally, the area of power systems in which specific electronic components are used will be indicated.

Coating the inner surface of grounded enclosures has been used to inhibit metal particle motion inside AC GIS for many years. However, for DC GIS, only fundamental research has been performed, while very few attempts have been made on real DC GIS. This paper reviews the basic research into the inhibition of metal particles by coating at DC. On this basis, based on a ±550 kV DC GIS busbar, an inhibition test of metal particle motion using coating was performed. Four types of metal particles were used as samples to verify the inhibitory effect of the grounded enclosure coating. The results showed that the coating has a very good inhibitory effect on block and powder metal particles on real GIS, and there are rarely any metal particles moving again under the rated DC voltage. However, for wire and flake metal particles, the effectiveness of the coating depends on the way the particle contacts the ground electrode when they are still, and ~30% of wire and flake metal particles can be inhibited. The conclusion of this paper is of guiding significance for the research and development of stable and reliable DC gas-insulated equipment. Full article
