Optimal battery chargers for photovoltaic system based on Fuzzy theory and Taguchi method is presented. Applying Fuzzy theory to the battery charging systems, the charge time can be reduced and the charge efficiency can be improved. The Taguchi parameter design method is utilized to optimize the battery charging system for multistage constant(More)
This paper presents the development of fuzzy controller for induction heating temperature control. Induction heating coil can be controlled by single phase sinusoidal pulse width modulation (SPWM) digital signal processor (DSP)-based inverter. DSP is used to store the required commands for generating the necessary waveforms to control the frequency of the(More)
This paper demonstrates an optical fiber sensor using a fiber Bragg grating (FBG) to measure real and reactive powers. The sensor head is based on FBG encapsulated in a metal cylinder embedded a magnetic material at measure point. The operating mechanism is the sensor can be attracted by the induced magnetic force created by the apparent power in the(More)
Abstract: A DC microgrid (DC-MG) is a novel power system that uses DC distribution in order to provide high quality power. The study system is made by a photovoltaic array (PV), a wind generator (WG), a fuel cell (FC), and an energy storage system (ESS) to establish a small type DC microgrid, with the bus being established by DC/DC converters with fuzzy(More)
