Abstract
A protection switching circuit includes a plurality of ferrite modules arranged in a matrix, wherein the matrix includes a plurality of columns and a plurality of rows. The protection switching circuit further includes a primary control module configured to select a specific ferrite module to be polarized and a redundant control module configured to select a specific ferrite module to be polarized, wherein the redundant control module is used when the primary control module is not used. The protection switching circuit further includes a plurality of first switches, wherein the plurality of first switches couples the plurality of columns of the matrix to a first and second charging circuit. The protection switching circuit further includes a plurality of second switches, wherein the plurality of second switches are organized into pairs, wherein each pair in the plurality of second switches couples a respective row of the matrix to a reference potential.
