A transformer winding contains a four-layer primary winding and two two-layer secondary windings. Each layer of the primary winding carries a total current I. Each layer of secondary winding #1 carries a total current 1.5. Each layer of secondary winding #2 carries a total current 0.5. All currents are sinusoidal. The effective relative conductor thickness is 2. The windings are partially interleaved in the following order: two primary layers, followed by both layers of secondary #1, followed by both layers of secondary #2, and finally the two remaining primary layers. Sketch an MMF diagram for this winding arrangement.
