Research and Modeling for Bi-Directional DC/DC Converter Based on Formation Technology for Lithium Battery
This paper puts forward a new kind of bidirectional DC/DC topological structure which is used in technology of lithium batteries .It adopts two-stage bidirectional topological structure which called half-bridge bidirectional converter and buck-boost bidirectional converter. This structure can achieve the transformation in the case of large voltage difference between input voltage and output voltage by DSP taking control of buck-boost bidirectional converter. This topological structure is authenticated in the environment of MATLAB/SIMLINK .The result demonstrates that the converter is stable, and can effectively realize bi-directional transformation between 3V battery voltage and 400V bus bar voltage.
