    Integrated Magnetic Components (IMC) combine multiple discrete magnetic elements into a single device to reduce size and improve power density. This work explores the use of magnetic shunts to integrate the series inductance into a planar transformer of a Dual Active Bridge (DAB) converter. This integration allows the control of the leakage inductance of the transformer, while reducing the size of the magnetic devices. A fully interleaved winding arrangement is employed, which minimizes power losses from the proximity effect. A general analysis of the Integrated Magnetic Component with Magnetic Shunts (IMCMS) magnetic circuit is developed, deriving a simplified model to accurately estimate the leakage inductance. Furthermore, it explores the magnetic flux behavior of the component, describing the effects of adding the magnetic shunts and the considerations to prevent saturation. A power analysis is presented, comparing this proposal with a conventional design composed of a transformer and an external inductor. Experimental validation is provided using a DAB converter operating over an input voltage range of 35–50 V and an output voltage range of 180–300 V and a power of 1.1 kW.
