  • Publication number: 20140091890
    Abstract: In an electrical energy generator, at least one permanent magnet generates flux and a magnetizable member forms the single flux path. An electrically conductive coil is wound around the magnetizable member, and a plurality of flux switches are operative to sequentially reverse the flux from the magnet through the member, thereby inducing electrical current in the coil. An alternative configuration uses stacked loops and a separate piece of material acting as the magnetizable member. One end of the magnet is coupled to one of the loops, with the other end being coupled to the other loop. Each loop further includes two flux switches operated in a 2×2 sequence to sequentially reverse the flux through the magnetizable member.

  • Publication number: 20130181800
    Abstract: A magnetic power converter has a core that has at least a first leg and a second leg. In addition, the magnetic power converter has an output coil positioned around the second leg and a toroid integrated into the first leg, the toroid comprising a permanent magnet and an first input coil, the input coil positioned relative to the permanent magnet, such that when an alternating current (A/C) is applied to the first input coil, permanent magnet magnetic flux produced by the permanent magnet is displaced and travels through the second leg.

  • Patent number: 8416045
    Abstract: A rare earth magnet is observed to function as a constant flux generator until coerced. To exploit this law, a Magnetic Power Converter is configured as a figure eight shaped balanced reluctance bridge where a rare earth magnet provides a source of constant flux employed as a working fluid. One side of the bridge drives an output coil and the other side is moderated by a toroid shaped control core acting as a variable reluctance shunt with respect to the magnet. Current in the control coil determines the rate and degree of flux variation across the bridge and therefore the resultant output voltage. Due to a mitigation of Lenz effect, full output loading is not reflected in the input; this property supports real power conversion efficiencies that may have wide applications in alternative energy and green energy generation.

  • Patent number: 8407883
    Abstract: A damascene process is utilized to fabricate the segmented magnetic core elements of an integrated circuit inductor structure. The magnetic core is electroplated from a seed layer that is conformal with a permanent dielectric mold that results in sidewall plating defining an easy magnetic axis. The hard axis runs parallel to the longitudinal axis of the core and the inductor coils are orthogonal to the core's longitudinal axis. The magnetic field generated by the inductor coils is, therefore, parallel and self-aligned to the hard magnetic axis. The easy axis is enhanced by electroplating in an applied magnetic field parallel to the easy axis.
