Adaptive Hysteresis Band Current Controller for the Shunt Active Power Filter Using the d-q0 Reference Frame Theory
Abstract: Recent wide spread applications of power electronic equipment has caused an increase of the harmonic disturbances in the power systems. The nonlinear loads draw harmonic and reactive power components of current from AC mains. Here an adaptive hysteresis band current controlled shunt active power filter is presented to eliminate harmonics and to compensate the reactive power of three-phase rectifier. This current controller changes the hysteresis bandwidth according to modulation frequency, …

Investigations on the impact of modulation formats and weather conditions in FSO link employing polarization division multiplexing and coherent detection-orthogonal frequency division multiplexing
Abstract: Free space optics (FSO) is a communication system where free space acts as medium between transceivers and they should be in line-of-sight for successful transmission of optical signal. Medium can be air, outer space, or vacuum. This system can be used for communication purpose in hours and in lesser economy. There are many advantages of FSO like high bandwidth and no spectrum license. The transmission in FSO is dependent on …

Modelling of DC-DC Adapter use Intent of Photovoltaic Module Coordinating with Load
Abstract: The particularities of using different types of DC-DC converters for the purpose ofmaximizing the power flow from the array to the load is analyzed in this paper. It has shown that the selection of the converter depends on the ratio of internal resistance of thephotovoltaic module to the load resistance. In order to always select the maximum possible power from the array, its output current has to be direct.Keywords: DC-DC …
