Independent Double-Boost Interleaved Converter with Three-Level Output

This paper introduces a novel converter topology based on an independent controlled double-boost configuration. The structure was achieved by combining two classic boost converters connected in parallel at the input and series output. Through proper control of converters, interleaved obtained, which presents low ripple for current. Being output, three-level attained with twice voltage gain topologies. A significant feature proposed is possibility operation integrated both symmetrical asymmetrical modes. may be particularly useful balancing or interconnection bipolar DC grids/applications. principle, simulations, mathematical analysis, laboratory prototype experimental results are presented.
