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)
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 controllers.(More)
The aim of this paper is to develop a study of Taguchi optimization method for a switching mode DC power supply with power factor corrector (PFC). Power factor and efficiency are the basic indicators for both of power quality and power saving. To attain these two factors in switching mode power supply design is the goal for power engineers. The most effects(More)
