Analysis of Non-isolated Bi-directional DC-DC Converter for Battery Charging Application

Abstract

High efficiency and uninterruptible power supplies are the main factors aiding to a lot of attention for bidirectional DC/DC converters. In this paper a bi-directional DC/DC converter (BDC) for battery charging applications is presented. The converter configuration has provided a way to charge between the batteries of two different energy storage systems (ESS). In this work a non-isolated bi-directional DC/DC converter is designed which possess high efficiency with respect to the isolated topology of bidirectional DC/DC converter. The controlling techniques discussed in this paper is used to charge the battery in the bidirectional fashion for which the BDC is employed. MATLAB/Simulink platform is used to perform the simulations. The simulation end results ensures the implementation of bi-directional charging of the batteries.
