        "Magnetic integration combines two or more discrete magnetics (DM) on one magnetic core. Coupling and parameter design support integration and miniaturization; fewer connection points reduce terminal losses in high-current circuits."

        "Brochure states that customer-specified short-circuit impedance is available, normally 5%–30%, for isolation or autotransformer designs, single-phase or three-phase. Leakage-inductance calculation determines main and auxiliary core cross sections, auxiliary-core air gaps, temperature rise and size. A foil-winding machine is customized for double-core transformer windings."
