  • Publication number: 20240175948
    Abstract: A current detection apparatus includes a magnetic sensor, configured to sense a magnetic field change of a to-be-tested current path, and convert the magnetic field change into an electrical signal; and a magnetically conductive unit, including a magnetically conductive material. The magnetically conductive unit is disposed on at least one of the following positions: a left side of the magnetic sensor, a right side of the magnetic sensor, and an upper side of the magnetic sensor, and the left side and the right side of the magnetic sensor are a left side and a right side of the magnetic sensor along the to-be-tested current path.

  • Patent number: 11993576
    Abstract: The invention provides an N-benzyl-N-arylsulfonamide derivative, which is an N-benzyl-N-arylsulfonamide compound represented by formula (I) or a pharmaceutically acceptable salt or solvate thereof. The N-benzyl-N-arylsulfonamide derivative is obtained by condensing a substituted nitrobenzene with 5- or 6-membered nitrogen-containing aliphatic heterocycle (the ring B), reducing the nitro group to an amino group, and subjecting the amino group to reductive amination, sulfonamidation; or by subjecting a substituted nitrobenzene to nitro reduction, reductive amination and sulfonamidation, and condensing the resultant intermediate with 5- or 6-membered nitrogen-containing aliphatic heterocycle (the ring B). It has been experimentally demonstrated that the N-benzyl-N-arylsulfonamide derivative of the invention can specifically bind to Kv1.3 potassium channel and inhibit or decrease its activity, and is useful in the treatment of autoimmune diseases caused by abnormal activation of the Kv1.

  • Publication number: 20230154671
    Abstract: A matrix transformer, a power converter, and a matrix transformer winding arrangement method. Each of the magnetic core columns of n sub-transformers of the matrix transformer is wound with a first winding and a second winding, first windings are used to form a high-voltage-side winding of the matrix transformer, and second windings are used to form a low-voltage-side winding of the matrix transformer. A ratio of a turn quantity design value of the high-voltage-side winding to the quantity n of the sub-transformers is not an integer.
