When a emergency occurs in the solar power generating, to confirm that there is a possibility of arcing. As long as there is solar radiation, solar power generation keeps supplying the electric power. Therefore if the arc occurs, there is a risk of fire. However, protection device for protecting a direct current system side was not present. We have developed a protective device for performing emergency...
The increasing market of mobile phones, has increased the need for electricity to power mobile phones, as well. This paper investigates the possibilities to charge a mobile phone by harvesting energy from the surroundings. Some technologies are better suited for this purpose than others. Through previous analyses solar cells and electromagnetic generator were found to be the most suitable solution...
An electrical vehicle charging station is a charging power supply for electrical vehicles. This paper proposes design of a model for a PV based electrical vehicle that forecasts total power output under particular conditions of Ankara city. First PV cell parameters are determined and then PV array formed including cells designed in order to calculate cumulative effect. Using actual irradiation and...
In this paper a resonant voltage doubler circuit is reported on, which enables high efficiency and low power consumption of a solar cell DC-DC converter (PV converter) for solar cell input. We have also developed a PV converter that uses a resonant voltage doubler circuit and achieved high conversion efficiency of 97.6% at an output power of 10kW.
Communication relay stations often suffer from common-mode noise generated by high speed switching in a boost chopper equipped for power supply. This problem can be addressed by applying soft-switching techniques to the boost chopper, although this can lead to significant increase in the circuit volume. To address this difficulty, this paper proposes a novel passive regenerative turn-off snubber applicable...
