Abstract
The objective of this paper is to propose a multi-input power converter for hybrid System in order to simplify the power system and reduce the cost. The proposed converter interfaces two unidirectional input power ports and a bidirectional port for a storage element in a unified Structure. This converter is interfacing for hybridizing alternative energy sources such as photovoltaic (PV) source, fuel cell (FC) source, and battery. The dc-dc boost converter is useful for combining several energy sources whose power capacity (or) Voltage levels are different. The proposed structure Utilizes only 4 power switches that independently Controlled with four different duty ratios, tracking The maximum power of the PV source, setting the FC power, controlling the battery power, and regulating the output voltage are provided. The disadvantage is that PV Generation depended on weather Conditions. An LC filter also is necessary to filter the output current and voltage from the harmonics and protect the grid from their destructive effect. The integration of the hybrid power system is implemented and simulated using MATLAB Software.
