Abstract
A sawtooth current fed to a cathode ray tube horizontal deflection coil is linearized with a structure including first and second saturable cores respectively coupled to the north and south pole sides of a single permanent magnet. The permanent magnet is interposed between the cores so that a magnetic flux caused by the permanent magnet passes through the first and second saturable cores in series. First and second windings, respectively wound on the first and second saturable cores and connected in series with each other, are arranged such that, when a current flows through them in one direction, a magnetic flux induced by the first winding in the first core is added to the magnetic flux coupled by the permanent magnet in the first saturable core and the magnetic flux coupled by the permanent magnet to the second core is subtracted from magnetic flux induced by the second winding in the second core.
