| Abstract |
This paper presents a parallel-connected Single Active Bridge (SAB) dc-dc converter for high-powerapplications. Paralleling lower-power converters can lower the current rating of each modular converterand interleaving the outputs can significantly reduce the magnitudes of input and output current rippleswithout increasing switching losses or device stresses. Analysis of both the input and output currentcharacteristics and design aspects of the transformer, the filter inductor, and the input and output filtercapacitors will be presented. Considering the high maintenance cost and fault tolerant requirements,this modular converter concept is expected to be highly beneficial especially for the offshore wind farmapplication. |
