In this paper, a type of renewable energy, PV system is proposed. The system is implemented in water heating. The main objective is to build a PV heating system which is able to absorb solar energy and convert into electrical energy; with the available electrical energy, thermal energy is produced. It is an off-grid system. The system consists of PV panel, controller, battery, inverter and heating...

Paper makes a brief analysis of the current solutions for supplying electricity to self services of electrical stations and proposes new, modern solutions, based on renewable energies. Analyzed solutions propose the use of integrated systems for the supply of energy, in which the heart is combustion pile, energy storage being made in hydrogen form. To make it possible the feeding both of DC and AC...
Renewable energy sources, such as solar energy and fuel cells, are desirable due to their pollution-free property. In order to utilize the present infrastructure of the utility grid for power transmission and distribution, grid-connected inverters are required for distributed generation systems and should have high reliability. However, shoot-through problem exists in the conventional bridge-type...
