Design and Realization of a Bi-directional DC/DC Converter in photovoltaic power system

Abstract

A energy storage device is essential in photovoltaic power system. The battery charge and discharge is a typical bidirectional DC / DC converter. According to design requirements, Buck/Boost DC/DC has been selected as the main circuit topology. The parameters of components have been set. The method of the double closed loop is designed and ensures the converter stable and efficient. The converter is realized and shows the accuracy of the design and the reliability of the control.
