Abstract
A thin resonant transformer includes a wire bobbin having a spool, an inner winding wound around the spool, a magnetic plate mounted in the wire bobbin, an outer winding wound in the wire bobbin and encompassing the inner winding and the magnetic plate, and two symmetric magnetic cores mounted on the wire bobbin. The wire bobbin has a top provided with a top plate and a bottom provided with a bottom plate. The magnetic plate is arranged between the inner winding and the outer winding. The inner winding, the outer winding, and the two magnetic cores generate a first magnetic circuit. The magnetic plate, the inner winding, and the outer winding generate a second magnetic circuit.
