Title:
METHOD FOR ACHIEVING CONVERTER TRANSFORMER FOR SUPPRESSING DC BIAS MAGNET
Document Type and Number:
WIPO Patent Application WO/2010/148575
Kind Code:
A1
Abstract:
A method for achieving converter transformer for suppressing DC bias magnet comprises increasing the seaming width of the transformer core lamination, which comprises in detail calculating the width and the height of each stage of lamination according to the reserved seaming width of the lamination, the sectional area of the core, the space between columns, and the height of the window, shearing the lamination based on the width and the height of the lamination obtained by calculating, overlapping two pieces of laminations into one piece of lamination according to the order of stages, placing them on the core frame alternately by stages, after overlapping all the laminations, fastening each stage of lamination.
