IET Power Electronics, EarlyView., 2023 This article presents a Fifteen‐level inverter topology that has a lesser number of switches (12) and can accommodate isolated DC sources. The total harmonic elimination (THD) of the proposed topology using genetic algorithm is within the IEEE 519 standards. Further, the fifteen‐level inverter is implemented in Hardware and firing pulses were generated

A Soft-Start-Based Method for Active Suppression of Magnetizing Inrush Current in Transformers
Electronics, 2023 The occurrence of high-amplitude magnetizing inrush current during the energization of a transformer without load poses significant challenges to the stable operation of both the transformer and the power grid, potentially leading to malfunctions in ...

Polytechnic and design, 2018 U ovom radu opisani su fenomeni i problemi do kojih dolazi prilikom priključenja transformatora na elektroenergetsku mrežu. Prilikom direktnog priključenja transformatora na mrežu (čak i u praznom hodu) dolazi do pojave visokih tranzijentnih iznosa struje koja može imati razne negativne posljedice. Tranzijentna struja može imati iznos i do desetak puta

Energies, 2021 When the electromagnetic transients occur in a power transformer, an inrush current is generated in its winding. The inrush current not only affects the performance of the transformer windings, but also affects the lifetime of the transformer.
