“…The dc link voltage V dc is constant due to the buck stage control system. The battery is modeled as a internal resistance R bat in series with a capacitance C bat , which is obtained in (10). The plant for this control system is formed by (9) and the closed-loop transfer function CLTF Vi (s) obtained in (6).…”

“…The use of semicontrolled rectifiers as in [7] and [8] represents good solutions to improve the power factor in electrical machines, but the inclusion of extra switches and current sensors may cause the battery charger cost to increase significantly. PWM rectifiers are also a prominent solution [9] [10], but they are more appropriated in medium and large systems due to high implementation cost.…”

This paper presents the analysis, design, simulation, and experimental results for a three-stage static power converter for battery charging feasible to small wind energy conversion systems (SWECS). The system employs a boost converter cascaded with a Graetz bridge, that allows the implementation of a Maximum Power Point Tracker (MPPT) and the reduction of the mechanical speed under overvoltage conditions across the batteries. Besides, a buck converter is connected in series with the boost stage to ensure a constant voltage bus between the aforementioned topologies. Thus, it is possible to extract the maximum power over the entire wind speed range, and battery charging can be realized through conventional techniques. The complete design of the proposed battery charger including power, control, and supervisory circuits are presented and developed, considering a 300 W system, with the possibility of charging battery banks rated at 12 V or 24 V. Simulation results are presented to prove the existence of maximum power points in the wind generator. Finally, experimental results of the developed prototype required to validate the functionality of the proposed study are presented and discussed.

“…Solar energy is prevalent popular choice of clean, recyclable renewable energy as they are more environmental friendly. Unfortunately, the optimal utilisation of the photovoltaic [5][6][7] energy is a major drawback with the conversion efficiency being in the range of 8 to 16 percent. This percentage is even lower with lesser radiation from the sun due to the improper weather conditions.…”

The photovoltaic system uses the photovoltaic array as a source of electrical power for the direct conversion of the sun's radiation to direct current without any environmental hazards. The main purpose of this research is to design of a converter with Maximum Power Point Tracker (MPPT) algorithm for any typical application of soil humidity control. Using this setup the major energy from the solar panel is used for the control of soil humidity. The design of the converter with MPPT together with the soil humidity control logic is presented in this paper. Experimental testing of the design controller is implemented and evaluated for performance under laboratory environment.

“…This research work validates the use of a Unity Power Factor Rectifier, consisting of a traditional diode bridge configuration with a parallel bank of bi-directional switches, as the front-end converter in a WECS. This AC-DC converter is based on Vienna Topology that is very popular in the Telecommunication industry because it leads to high power density of three-phase AC supplies [6]. The use of a Vienna rectifier in a stand-alone wind energy conversion system WECS scenario is not previously investigated.…”
