US Patent 9837923 Integrated power converter and transformer

A power converter for a power system includes an input ceramic layer, an output ceramic layer, an input stage coupled to the input ceramic layer, an output stage coupled to the output ceramic layer, and a planar transformer coupled between said input stage and said output stage. The input receives a power input and the output stage generates a power output at least partially as a function of the power input. The planar transformer includes an input winding coupled to the input stage and an output winding coupled to the output stage. The input winding has a plurality of input turns and the output winding has a plurality of output turns. The input turns interleave the output turns.
