A Flyback transformer is a high-voltage, high-frequency transformer used in plasma balls and with cathode-ray tubes (CRTs). It provides the high (often several kV) anode DC voltage required for operation of CRTs. Variations in anode voltage supplied by the flyback can result in distortions in the image displayed by the CRT.
High-frequency transformers operating in the tens to hundreds of kilohertz often have windings made of braided Litz wire to minimize the skin-effect and proximity effect losses. Large power transformers use multiple-stranded conductors as well, since even at low power frequencies non-uniform distribution of current would otherwise exist in high ...

The high frequency used permits the use of a much smaller transformer. In television sets, this high frequency is about 15 kilohertz (15.625 kHz for PAL, 15.734 kHz for NTSC), and vibrations from the transformer core caused by magnetostriction can often be heard as a high-pitched whine.
Jan 15, 2024 · High-frequency transformers are essential in modern electronics, managing power distribution at frequencies beyond standard transformers. Selecting the right core material is pivotal; it profoundly affects efficiency and performance.
Jul 1, 2020 · There are two choices for high-frequency inductors or transformers, i.e. with a magnetic core and without magnetic core (air core). With the help of the magnetic core, the volume can be greatly reduced compared with the air core one under the same inductance in ideal condition, as well as the magnetic field can be well controlled.

High Frequency Transformers: Basic Principles. High-frequency transformers operate using the same basic principles as standard transformers. The primary difference is that, as their name implies, they operate at much higher frequencies — while most line voltage transformers operate at 50 or 60 Hz, high-frequency transformers use frequencies ...
High Frequency TRANSFORMERS In part A we will focus on transformers and the relation between magnetic and electrical properties. We then use the information gleaned from relating the copper wire turns loss of a transformer to more accurately treat the case of an inductor which carries only AC currents in
