  • Patent number: 10600542
    Abstract: A polarity-switching magnetic diode provides a method of gating or “rectifying” N and S polarized flux contained within the closed-loop flux circuit of a magnetic flux element. Gaps separate the opposing magnetic polarities, and strategically placed control coils are disposed to break the magnetic circuit in at least two places upon electrical activation of the device—forming high density flux zones of opposite polarity. Switching the control coil's magnetic flux flow allows for the high density flux zones to alternate N and S polarity.

  • Patent number: 10573445
    Abstract: The present subject matter relates to the control of electromagnetic fields and has particular relevance to wireless power transfer system devices and systems. In particular there is provided a magnetic flux coupling apparatus comprising a coil for generating or receiving magnetic coupling flux; and a leakage flux element separated from the coil by a region of relatively low magnetic permeability and positioned to provide a controlled path for leakage flux independent of coupling flux; wherein the leakage flux element comprises a lossy magnetic material of relatively high magnetic permeability which absorbs energy from a time varying magnetic field to thereby alternate attenuate leakage flux. The apparatus as disclosed herein aids in the suppression of the magnetic flux that leaks out of the air gap in such systems, or which leaks out of a region where magnetic flux is required for inductive power transfer.

  • Patent number: 10566157
    Abstract: A heavy current reed switch contact structure comprises at least one set of elastic reed electrode (11, 12) or at least one fixed electrode (12) and an elastic reed electrode (11). The reed electrode (11, 12) is made of a conductive material. Contacts (13, 14) are arranged on opposing surfaces of mutually overlapping ends. A side of the end having the contacts is disposed with an arc discharge device (16, 162). The reed switch employs a specially designed contact structure, and the arc discharge structure device is additionally disposed on the basis of a traditional switch contact structure. As a result, the reed switch quickly transfers to the contact arc discharge structure device an instantons arc generated upon switching the switch contact, thereby easing burnout resulting from an arc on the contact surfaces of the contacts, enabling the contacts to be less prone to being adhered together, and considerably increasing a bearing current and a switching capacity of the reed switch.
