Analysis of Switching Topology for Advanced Isolated Bi-Directional DC-DC Converter

In this paper, the controlling methods of IBDC is analyzed which increases the overall performance of the IBDC. The IBDC power conversion is based on the high frequency link because it has many advantages over low frequency power conversion like reliability, less noise without effecting efficiency, high power density, light weight and cost. The usage of IBDC is continuously increasing for the various applications for the interfacing of the renewable energy resource to the HEV, UPS and utility grid systems. The power conversion is controlled by the using various phase angle control strategy. In this phase angle control strategy, the phase shift is provided between the input and output side of the transformer. For increasing the efficiency, different control strategy is used the discussed method are the basic of the controlling of IBDC other control strategy may be derived from these discussed methods. The analysis of control strategy has been done and discussed the strategy which increases the efficiency and the other factor.
