Abstract

PURPOSE:To decrease transmission of pulse noise significantly and reduce capacitance of a line filter, by a method wherein electrostatic shield is applied to a primary and a secondary windings in mutually insulated state. CONSTITUTION:A secondary winding 3 is wound at inside of EI type core 1 through an insulation paper 2, and a primary winding 4 is wound around the secondary winding 3 in concentric form. A secondary electrostatic shield foil 8 and a primary electrostatic shield foil 9, having an insulator 5 interposed therebetween, are inserted and wound between the windings 3, 4 through insulation papers 6, 7 respectively. Another secondary winding 3' is wound outside the primary winding 4. Between the windings 4, 3' are wound an insulation film 7', a primary electrostatic shield foil 9', an insulator 5', a secondary electrostatic shield foil 8' and an insulation paper 6' in order. Both secondary windings 3, 3' constitute parallel circuit. Direction of leakage flux is reversed between both secondary windings 3, 3' thereby leakage inductance decreases.
