Abstract

FIELD: electrical engineering; high-frequency transformers (inductive components) for radio electronics and converter engineering, such as secondary power supplies. SUBSTANCE: matrix transformer has several similar sections incorporating open core-type magnetic circuit with primary and secondary windings coaxially wound on its surface; leads of mentioned similar windings of sections or groups combining one or more sections are connected into combination of series and parallel and adjustment magnetic coupling is provided between sections. EFFECT: enlarged functional capabilities due to control of transformer ratio, magnetizing circuit flux density, and winding-to-winding capacitance attained by switching the windings and varying magnetic coupling between sections at constant parameters of cores and windings. 2 dwg

Изобретение относится к электротехнике, в частности к высокочастотным трансформаторам (индуктивным элементам) и может использоваться в радиоэлектронике и преобразовательной технике, например в источниках вторичного электропитания. Матричный трансформатор имеет более широкую область применения за счет возможности регулирования коэффициента трансформации, индуктивности намагничивающего контура и межобмоточной емкости, что достигается путем коммутации обмоток и изменением магнитной связи между секциями при неизменных параметрах сердечников и обмоток. Устройство состоит из нескольких одинаковых секций, содержащих незамкнутый стержневой магнитный сердечник с коаксиально расположенными на его поверхности первичной и вторичной обмотками, причем соединения выводов указанных одноименных обмоток у секций и групп, объединяющих одну или несколько секций, выполнены в виде комбинаций последовательных и параллельных схем, а между секциями имеется регулируемая магнитная связь. 2 ил.The invention relates to electrical engineering, in particular to high-frequency transformers (inductive elements) and can be used in electronics and converting technology, for example, in secondary power sources. The matrix transformer has a wider scope due to the ability to control the transformation coefficient, the inductance of the magnetizing circuit and the winding capacity, which is achieved by switching the windings and changing the magnetic coupling between the sections with the same parameters of the cores and windings. The device consists of several identical sections containing an open rod magnetic core with primary and secondary windings coaxially located on its surface, and the connections of the terminals of the same windings of the sections and groups uniting one or more sections are made in the form of combinations of serial and parallel circuits, and Between sections there is an adjustable magnetic coupling. 2 ill.
