Abstract: The developing worry about the deficiency of petroleum products, the expansion in oil costs, expanded an Earth-wide temperature lift, obliteration of nature prompted the utilization of energy units and sustainable power source power generation. Such force age requires a lift DC-DC converter with high voltage change proportion and high proficiency. A DC-DC lift converter with voltage multiplier cell is proposed in this paper. The proposed configuration comprises a converter with helper capacitors and diodes. VMC proposed in this paper gives high voltage put on by decreasing the voltage weight on diodes and switches. This converter is easy to execute and furthermore financially savvy.......

Abstract: Border traps or near-interface traps in the amorphous insulator such as thermal silicon dioxide or silicon nitride near the semiconductor conduction band of a metal-insulator-semiconductor device are known to limit the field effect mobility of a field-effect-transistor. Border trap densities in thermal silicon dioxide grown on silicon semiconductor at different high and low temperatures have been calculated at 300K by a new method proposed by the author in an earlier study. The border trap density in the oxide grown on silicon at high temperature with no annealing is found to correlate to the border trap density in oxide on 4H-SiC by a factor of three before nitridation. The new method used for the calculations of the trap densities is based on the concept of displacement current due to a changing electric field across a capacitor. It is put forth in a concise manner in the theory section of the article.

Abstract: Concerns associated with the delivery of electric and magnetic field (EMF) emissions through mobile communication cellular services from most cellular base transceiver stations (BTSs) prompted this work, as it is supposedly linked to health hazards. This research article assesses and analyses the Radio Frequency ElectroMagnetic Radiation (RF EMR) emitted by mobile cellular BTS antennas within Geidam town. With the 3-axis RF field strength meter, measurements of the RF electric field intensity, and RF EMF power density were carried out from the BTSs at distances of 10, 20, 30, …, 100 metres within a frequency range 900 MHz to 8 GHz. Results obtained shows that the RF.......

Abstract: Micro generators are suitable replacement for limited life power supplies which could supply electronic devices. This method of energy harvesting converts mechanical vibrations into electrical output power. Electromagnetic transduction method has more advantages in comparison with other methods and it is considered to be applied in this work. The output voltage of micro generator is depended on input mechanical acceleration. Analysis of output voltage could estimate the input acceleration. In this work, transient response of micro generator is studied to achieve input mechanical acceleration. For this purpose, RBF (Radial Basis Function) Artificial Neural Network (ANN) is trained with transient output voltage of power harvester to estimate the input mechanical acceleration. The results illustrate that, combination of electromagnetic micro generator model with ANN could be an applied and innovative sensor to estimate mechanical acceleration.
