摘要： A transformer includes: an upper primary substrate (110) which is formed by stacking a plurality of dielectric substrates, each substrate being provided with spiral conductive patterns; a lower secondary substrate (120) which is formed by stacking a plurality of dielectric substrates, each substrate being provided with spiral conductive patterns, in which the lower secondary substrate is positioned below the upper primary substrate (110) in such a way that the lower secondary substrate comes into contact with the upper primary substrate (110) or is spaced apart from the upper primary substrate (110); and a secondary coil element (200) of a planar shape to produce an induced current by a current applied to the upper primary substrate (110) and the lower primary substrate (120).

摘要： A transformer and an LLC resonant converter are provided. The transformer includes first and second cores configured to include a pair of outer foots and a middle foot positioned between the outer foots, and to induce a magnetic field formation; first and second inductor winding parts configured to include a conductor surrounding a circumference of each of the pair of outer foots of the first core, and to be connected in series with each other; and first and second transformer winding parts configured to include a conductor surrounding a circumference of each of the pair of outer foots of the second core, wherein the pair of outer foots of the first core face the pair of outer foots of the second core, the middle foot of the first core faces the middle foot of the second core, and the first core and the second core are disposed to be spaced apart from each other.
