<p>The invention relates to reverse transformers configured on several ferromagnetic cores divided by an air gap. A magnetizing winding is configured on only one or a part of the cores, forming a magnetizing inductor. When a current is supplied to the magnetizing winding, the ferromagnetic core of the inductor is magnetized, as are the neighbouring cores via the air gap. The air gap is selected so that a significant part of the magnetic field of the cores is closed across the air, forming a secondary magnetic leakage field. Part of the magnetic field of all the cores is closed across the magnetic circuit via the air gap, forming a common magnetic circuit and a common magnetic flux. The magnetic leakage field of the cores is closed outside the inductor and does not play a part in the magnetic interaction of said components, nor does it form a common magnetic flux linkage with the magnetizing winding of the inductor. Thus, it does not affect the establishment of a current in the inductor winding because it does not generate emf against the current during magnetization. The windings of the secondary cores encompass the entire magnetic field thereof and serve merely to convert all the secondary magnetic leakage fluxes into electrical energy during demagnetization. This results in a more complete conversion of all the magnetic energy in the structure into electrical energy.</p> |
