Abstract

The invention discloses a vertical-type transformer structure. The vertical-type transformer structure is different from a transformer structure in prior art. The vertical-type transformer structure is characterized in that an accommodating member is utilized for accommodating a bobbin which warps a primary-side coil. According to the vertical-type transformer structure, after a primary-side iron core is combined with the bobbin which is accommodated in the accommodating member, the accommodating member supplies effective insulation to the primary-side iron core so that a portion between the primary-side iron core and an adjacent electronic assembly can satisfy a related safety regulation. Furthermore, because the bobbin of the primary-side coil is accommodated and packaged by the central accommodating part of the accommodating member, after high voltage is input into the primary-side coil, the accommodating member supplies effective insulation to the primary-side coil, thereby preventing direct bypass of high voltage through an adjacent secondary-side iron core to the secondary-side coil.

Description

technical field [0001] The invention relates to the technical field of power electronics, in particular to a vertical transformer structure. Background technique [0002] With the evolution and development of electronic products, different electronic products need to be driven by different power supply devices; therefore, manufacturers of power supply devices are actively trying to develop various transformer structures for corresponding applications in various power supply devices . [0003] A simple transformer is composed of a first conductor and a second conductor, and when an indeterminate current passes through the first conductor, a fluctuating magnetic field is generated on the first conductor; then, based on the principle of electromagnetic mutual inductance, the fluctuation The magnetic field will cause an induced electromotive force to be generated on the second conductor, and then form a potential difference between the first conductor and the second conductor, ...
