Abstract
The present invention relates to a transformer and, more specifically, to a transformer including a secondary coil portion on which a conductive plate is stacked. A transformer according to one embodiment of the present invention can comprise: a bobbin; a core portion coupled to the bobbin along the outer side of the bobbin; and a plurality of conductive plates inserted into the bobbin and stacked in a thickness direction.
Claims18
A transformer comprising:
- a bobbin;
- a core unit disposed outside the bobbin, the core unit comprising an upper core having a first middle leg and a lower core having a second middle leg, the core unit having a gap between the first middle leg and the second middle leg;
- and
- a plurality of conductive plates stacked in a thickness direction, wherein
- each of the plurality of conductive plates has a side shape disposed spaced apart from the gap in a vertical direction.
