Comparative Study of Winding Arrangements for Power Electronic Transformers

The paper presents comparative study of winding arrangements for power electronic transformers. The designs are based on an improved design algorithm consisting of 15 steps. Four different winding arrangements are considered for a transformer design, 1200W, 25kHz. The approaches applied are interleaved windings, fully wound winding layers and using Litz wire. The material used is ferrite (N87). A set of operating and construction parameters is defined to compare the obtained designs. Design conclusions and recommendations are derived based on the comparison of the studied winding arrangements of transformers for power electronics.
