MATRIX TRANSFORMER Russian patent published in 1997 - IPC

FIELD: electric engineering, inductance elements of high-frequency transformers. SUBSTANCE: device has several identical sections each of which has open rod magnetic core on which surface coaxial primary and secondary windings are located. Joins of terminals of above-mentioned same-pole windings in sections and groups which join one or several sections are designed as combinations of serial and parallel circuits. Sections are also connected by means of controlled magnetic field. Device may be used in secondary power supply units for radio engineering and power converters. EFFECT: increased field of application due to possibility to control transformation rate, inductance of magnetic circuit and capacitance between windings. 2 dwg
