Abstract
An interleaved transformer or a transformer and integrated set of inductors formed via a magnetic structure comprising a set of E cores and an I core inserted between the set of E cores is provided in order to address issues that occur when a structured transformer is coupled together with inductor flux. Actual inductance exhibited by the transformers is controlled by a preselected precise gap between the I core and each of the E cores. The advantage of such a structured transformer cancels out the magnetic flux in certain legs of the magnetic structure requiring less magnetic material and thus, less core losses while improving the overall efficiency of a power supply.
