Energy Router: A Sustainable Solution for Future Residential Buildings
PublicationElectric energy consumption is increasing much faster than the predicted growth in energy generation. Although the installed capacity of renewable energy sources is also expanding, grid congestion remains unavoidable without adopting smart energy management systems (EMS) and flexible power electronics structures. Given the significant installed capacity of photovoltaic (PV) systems in the residential sector, moving towards zero-emission...

Isolated High Step-Up Current-Fed DC-DC Converter With Low Input Current Ripple and Wide Full-Soft-Switching Capability
PublicationThis paper presents a current-fed isolated, high step-up dc-dc converter that has low voltage stress on the power switches. The suggested configuration achieves isolation between the input and output using a High-Frequency (HF) transformer. The leakage inductance of the transformer is harnessed to achieve Zero Voltage Switching (ZVS) during power switch turn-on and Zero Current Switching (ZCS) for power diodes across a broad range...

Comparative Evaluation of Dual-Purpose Converters Suitable for Application in DC and AC Grids
PublicationThis article presents a comparative evaluation of several topological solutions to the universal power electronics interface for the dc or single-phase ac grids using the same terminals. The idea of a dual-purpose approach lies in the utilization of the same semiconductors in the dc–dc and the dc–ac configuration, resulting in minimal redundancy. Particular focus is on the power density improvement and control. Out of the three...

Concept of Wireless Low-Voltage DC Socket for the Residential House Application
PublicationThe proposed research is devoted to the comprehensive theoretical and experimental study of the concept of the wireless low power dc socket for residential applications. The main goal of this work is to provide safe dc source for residential customers at power level which is enough in order to supply all typical appliances without power factor correctors. Such types of devices can be already connected to the dc grid and decoupled...

Cost-Effective Piggyback Forward dc-dc Converter
PublicationThe novel piggyback dc-dc converter as a cost-effective solution is presented in this work. It provides a wide input voltage range of regulation with a low component count. The novel solution is an advanced forward dc-dc converter with an additional clamp output capacitor. The idea of such a type of converter is to transfer magnetizing energy of transformer to the output side, instead of using input clamp circuit. The design guidelines...

Day-ahead Solar Power Forecasting Using LightGBM and Self-Attention Based Encoder-Decoder Networks
PublicationThe burgeoning trend of integrating renewable energy harvesters into the grid introduces critical issues for its reliability and stability. These issues arise from the stochastic and intermittent nature of renewable energy sources. Data-driven forecasting tools are indispensable in mitigating these challenges with their rugged performance. However, tools relying solely on data-driven methods often underperform when an adequate...

Dc Leakage Current in Isolated Grid-Connected dc Nanogrid - Origins and Elimination Methods
PublicationThe LV dc system is a relatively new trend in the distribution sector, which seems to grow widely in the near future due to its promising advantages. In this context, LV dc protection and grounding are challenging issues. Although the galvanically isolated connection mode of dc nanogrid to the ac grid has high reliability, the leakage current can still be injected into the ac grid through the interwinding capacitors and the insulation...

Dual-Purpose Converters for DC or AC Grid as Energy Transition Solution: Perspectives and Challenges
PublicationWe present a novel concept of a dual-purpose power converter for dc or ac grids. These universal dc–dc/ac power electronic interfaces are suitable for application in the dc or single-phase or three-phase ac grids using the same terminals. The idea is to utilize the same semiconductors and passive components in the dc–ac and in the dc–dc configurations with minimal additional components and to maximize their effectiveness in any...
