Abstract

The renewable sources to convert the power by using power electronic converters, that is to match the load demand and grid requirement to improve the dynamic and steady-state characteristics of the green generation systems, to provide the Maximum Power Point Tracking (MPPT) control, to integrate the energy storage system to solve the challenge of the intermittent nature of the renewable energy and the unpredictability of the load demand. In order to improve the efficiency and the power density of the overall circuit, the use of a two port High Gain buck boost based DC-DC converter, which includes one for the renewable sources and another for the energy storage system is used. In recent years, many two port DC-DC converters have been proposed and reported in the literature. Each of these converters has its own topology and operating principle, which results in different complexities, different numbers of components, different reliability and efficiency. This work also explains the potential research extension of the basic topologies of DC-DC converters and how the voltage gain of the two-port DC-DC converter can be improved.
