Brochure states that integrating transformer and reactor magnetics increases power density and efficiency, reduces output ripple and improves transient output response, while reducing primary inverter-switch losses and magnetic-component size and losses.
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.
The principle diagram combines a discrete series inductance L and transformer T into an integrated T+L magnetic assembly; either arrangement of L relative to T is illustrated. Integrated filtering inductance with specified short-circuit impedance is offered for 1 kVA–1000 kVA.
