This paper presents a novel fully controlled, flexible and self-adjusting LED lighting PV-Battery powered scheme using a pulse-width modulation (PWM) switching. This scheme is controlled a dual-loop error driven, time descaled, weighted modified proportional-integral-derivative (WM-PID) control scheme for the photovoltaic (PV)-battery interfaced to the light emitting diode (LED) lighting load. It...
In this paper, sliding mode controlled Buck-Boost DC/DC converter powered by Photovoltaic (PV) module for battery charge system is given. The general design of the system is simulated using the Matlab/Simulink software and performed experimentally using Digital Signal Processing (DSP) and necessary circuits. The sliding mode control is realized based on the inductance current and the output voltage...
A synchronous buck DC–DC converter that can be used to produce hydrogen through electrolysis by using the energy generated from renewable energy sources has been designed and implemented. The reason for selecting this topology is that the voltage level at the output of renewable sources, such as solar cells and storage batteries, is about 12 V DC, and the voltage level required for electrolysis is...
In this study small signal analyses of a buck boost converter for a renewable energy applications is performed and hardware implementation is realized. State equations are solved for different study conditions and transfer function of uncontrolled system is obtained for stability analyses. Experimental hardware of buck boost converter realized with a MOSFET driver circuit which is designed for high...
In this paper, a fuzzy logic controlled buck-boost DC-DC converter powered by Photo Voltaic (PV) for Battery-Load system is presented. General design of the converter-load system is performed using Matlab/Simulink. In the FLC, different fuzzy membership functions are used and the results are compared with each other. The complete converter-load system has been developed, analyzed, and validated by...
In this paper, general information about, unionized radiation, wireless communication systems and electromagnetic fields are given. The safety of mobile phones has been evaluated in terms of specific absorption ratio (SAR). This SAR values have been defined discussing among international standard organizations. Electromagnetic Compatibility (EMC) measurements are made with a compact spectrum analyzer...
