| description | The invention relates to a switching power supply transformer combined magnetic core which comprises two or more first magnetic core bodies and one or more second magnetic core bodies. The section area of synthesis magnetic circuit magnetic bodies of the second magnetic core bodies is two or more times that of synthesis magnetic circuit magnetic bodies of the first magnetic core bodies. The size of magnetic columns of the second magnetic core bodies is twice that of magnetic columns of the first magnetic columns, and the magnetic columns of the second magnetic core bodies are symmetrically distributed on the two sides of the magnetic bodies of the magnetic core bodies. The magnetic columns on the two sides of the second magnetic bodies are not equal in length, and then winding windows on the two sides of the magnetic bodies are not equal in size. Primary windings or secondary windings of a transformer are wound around central magnetic columns of the first magnetic core bodies and the second magnetic core bodies respectively. By means of the switching power supply transformer combined magnetic core, the primary windings and the secondary windings of the transformer are completely insulated and isolated from each other, the problem that primary windings or secondary windings of a transformer of a conventional process are dual insulated and the problem that bad influences are caused by distributed capacitance of the transformer of the conventional process are solved, and the power supply transformer is low in leakage inductance and high in transmission efficiency. |
