In the framework of EUROfusion Horizon Europe Programme, ENEA and its linked third parties are in charge conceptual design steam generators belonging to EU DEMO WCLL Breeding Blanket Primary Heat Transfer Systems (BB PHTSs). particular, 2021, activities supporting numerical simulations were carried out order achieve a feasible robust preliminary concept Once Through Steam Generators (OTSGs), se...

Energy consumption in the buildings is responsible for 26% of Australia’s greenhouse gas emissions where cooling typically accounts for over 50% of the total building energy use. The aim of this study was to investigate the potential for reducing the cooling systems’ environmental footprint with applications of alternative renewable energy source. Three types of cooling systems, water cooled, a...

This paper reports on an electrostatic Vibration Energy Harvester (e-VEH) system, for which the energy conversion process is initiated with a low bias voltage and is compatible with wideband stochastic external vibrations. The system employs the auto-synchronous conditioning circuit topology with the use of a novel dedicated integrated low-power highvoltage switch that is needed to connect the ...

DC microgrid has been gaining popularity as solution a more efficient and simpler power system especially for remote areas, where the main grid yet to be built. This paper proposes based on renewable energy sources that employs decentralized control without communication between one point another. It can deployed an individual isolated unit or form expandable through bus better reliability effi...

Environmental protection initiatives are speeding up the replacement of present IC engine-based transportation system with an electric motor-driven system. In vehicles (EV), energy stored in batteries is used for traction vehicle and operation auxiliaries. The range was identified to be one major challenges faced by EV segment. optimization consumption best solution improvement EV. Auxiliaries ...

Several technologies are being used in distributed generation applications with variable degree of success. Among those are: wind turbines, small-scale hydropower plants, biomass, microturbines, photovoltaic arrays and fuel cells. In a fuel cell, the chemical energy incorporated in the fuel is converted directly to electricity and heat. Fuel cell technology is one of the most interesting energy...

A transcutaneous energy transformer system (TETS) can provide power to an implanted ventricular assist device (VAD) across an unbroken layer of skin. A TETS includes a subcutaneous secondary coil, which traditionally connects to remote power conditioning circuitry located to avoid eddy current losses and heating that occur in metal near operating TETS coils. Litz wire, used to construct the coi...

In order to utilize the energy from the renewable energy sources, power conversion system is necessary, in which the voltage source inverter (VSI) is usually the last stage for injecting power to the grid. It is an economical solution to add the function of power quality conditioning to the grid-connected VSI in the low-voltage distribution system. Two multifunctional VSIs are studied in this p...
