    Abstract: Wireless power transfer system plays a key role in the present and future days, because of their upgraded comfort and safety and their merits of less green-house gas (GHG) emissions, cell phones, laptops and electric vehicle charging. In this paper, the basic two resonance circuits were analyzed using an inductive wireless power transfer (IWPT) sys... Show More

    Abstract: To realize optical wireless power transmission, atmospheric propagation of eye-safe wavelength (1.57μm) laser beams was theoretically investigated. Laser beams are affected by the presence of water vapor and aerosols which absorb and scatter the laser energy. The scattering coefficients of water molecules and aerosols were estimated to be about 6.3... Show More

    Abstract: Ensuring a long battery life and satisfactory performance requires accurate charging cycles. There are three phases to the charge cycle - Constant Current Charge, Constant Voltage Charge, and Float Charge. It is usual that lead acid battery users complain about fast degrading performance because most the low cost commercially available lead Acid Ba... Show More

    Abstract: This research was conducted to verify the significance of the LCL-filter on the grid current and the impact of variable fault resistance values on the reactive power genereated in a grid-tied inverter. The stability of LCL-type grid connected inverter with capacitor current feedback in active damping state was evaluated in this paper. The effects o... Show More
