PURPOSE:To accurately transmit a pulse wave form by a method wherein a pair of opposing good conductive band-type materials are wound on a core through an intermediate of a dielectric and a capacitance is established at a prescribed value. CONSTITUTION:A winding 52 is formed by winding dielectrics 531 and 532, having a pair of copper band-type materials 541 and 542 bonded together opposing each other between them, on a leg 51 of an EI-type core and a transformer for a switching regulator is formed. A prescribed value for the capacitance between both band- type materials of the winding can be obtained by changing the width of a primary and a secondary band-type materials, without changing the inductance of the transformer itself. In addition, as adjustment can be made by selecting width and quality of material of the dielectric, a resonating transmission channel is constituted for signals of multiple odd number of a transmission palse fundamental frequency. As a result, a transmission efficiency is improved by an accurate transmission of palse wave forms and a higher harmonic noise is reduced by having a very small inductance. |
