Interleaving Technique Applied in an Active Filter Based on the Full-Bridge Cascaded Converter

In this paper, a cascaded-parallel interleaving concept using traditional single-phase full-bridge converter for medium- and high-current applications is addressed. Different structures composed by 6 traditional single-phase full-bridges are investigated. The modulation strategy is discussed. To evaluate the performances of proposed structures, the topologies are tested as shunt active power filters and a comparison study between the proposed topologies and conventional cascaded full- bridge, in terms of semiconductor power losses, is realized. Simulations results are presented.
