Design and Implementation of Full Bridge Non-isolated DC-DC Bidirectional Converter Using Fuzzy logic

Abstract

With ever increasing benefits of non-renewable energy sources, the importance of energy
storage system is increasing consistently. Power electronics converters are usually used to
convert the power from renewable sources to match the load demand and grid requirements
to improve dynamic and steady state characteristics of these green generation systems.
Therefore, there is growing importance in bidirectional DC to DC converters for interface
battery with energy sources. As DC to DC bidirectional converters can transfer the power
between two DC sources in either direction, these converters are widely used in renewable
energy hybrid power systems. Efficiency, economy and high conversion ratio are the some
challenges in the development of DC to DC converters. For the low voltage range, nonisolated DC to DC converters are suitable also; they are fit for DC micro grid voltage levels
