Implementation of Bi-directional Capabilities of Batteries for using Quadratic Buck-Boost Converter

Energy storage devices are essential to provide voltage and frequency stability in renewable energy sources, such as solar and wind. In this paper is used to distribute generating system like batteries super capacitors or discharging mode operating condition. In this paper, a new non- isolated bidirectional quadratic converter characterized by high voltage gain in both step-down (Buck) and step-up (Boost) operation modes is proposed. It is used to reduce ripple in distributed system. All these types permit an optimized operation among the DC bus and the storage devices. The bidirectional converter proposed in both condition modes step up and step down. The controller design as the fuzzy logic condition and performance of the proposed converter through simulation and experimental results.
