FIELD: power supply devices of digital hardware components with a high sensitivity to interference. SUBSTANCE: transformer has a magnetic circuit with the primary and secondary windings. Both windings are encapsulated in sheath 8 of resin with a high-frequency ferromagnetic filler. Installed between the primary and secondary windings is a screen of a sheet of current-conducting material with a slit shunted by a resistive component. The secondary winding is divided into sections, with magnetic shunts installed on the ends of each section, a magnetic shunt is installed between the sections. A screen of a sheet of current-conducting material is installed over the secondary winding with a sheath. It is a three-phase transformer with a three-core magnetic circuit, a coil with the primary and secondary windings is installed on the form on each core. EFFECT: enhanced reliability. |
