Abstract:
1. A biased gap inductor, comprising: a first ferromagnetic plate; a second ferromagnetic plate; a conductor sandwiched between the first ferromagnetic plate and the second ferromagnetic plate and bent around a front surface of the second ferromagnetic plate downwardly towards a bottom surface of the second ferromagnetic plate; and an adhesive between the first ferromagnetic plate and the second ferromagnetic plate, the adhesive comprising magnet powder to thereby form a first magnetic gap and a second magnetic gap on opposite sides of the conductor, the adhesive binding together the first and second ferromagnetic plates, the adhesive having a thickness of less than 500 um; wherein the adhesive is magnetized such that the magnet powder applies a steady state magnetic flux and the first magnetic gap is polarized in an opposite direction from the second magnetic gap.
