Four families of non-isolated single-switch Cúk, SEPIC, Zeta and Forward converters are derived. They incorporate coupled-inductor, voltage-doubler and voltage clamping circuits to accomplish a high DC voltage step-up at high-efficiency levels. Besides Cúk and SEPIC, Zeta and Forward can also have the advantage of operating with continuous input and output currents, which provide accurate tracking...
The proposal of this paper is to present and analyze a charging station PV system of battery (PV-CS) with a wide range of output voltage buses, where is possible to make the charge of the batteries at the maximum power point tracking (MPPT), which increases the PV utilization. In this paper, a complete analysis of the Zeta converter applied as a photovoltaic battery charger is carried out. The solar...
In this paper, a complete analysis of the Zeta converter applied as a photovoltaic battery charger is carried out. The design methodology of the solar battery charger system, including the power circuit main devices and system controllers are presented in details. The solar battery charger includes an alternative Constant Current/Constant Voltage (CC/CV) charging method with inherent Perturb and Observe...
