    Transformer. An O-core transformer consisting of two coils of copper wire wrapped around a magnetic core. In electrical engineering, a transformer is a passive component that transfers electrical energy from one electrical circuit to another circuit, or multiple circuits. A varying current in any coil of the transformer produces a varying ...

  2. V. VI. v. t. e. Very high frequency ( VHF) is the ITU designation [1] for the range of radio frequency electromagnetic waves ( radio waves) from 30 to 300 megahertz (MHz), with corresponding wavelengths of ten meters to one meter. Frequencies immediately below VHF are denoted high frequency (HF), and the next higher frequencies are known as ...

  3. Mar 26, 2018 · 2. High freguency isn't a well defined term. Most of us surely think that HF transformers are complex to design, analyze and make, because several non-idealities grow substantially as the frequency increases. For example many iron cores, which are excellent for 50Hz transformers, become awfully lossy when the frequency is only few kilohertz.

  5. The RF performance of these configurations is similar, however. The relationship of voltage and current between primary and secondary windings, as well as the terminating impedances, are given by the following equations. V = N V and I = I. 2 1 2 1 ÷ N, where N is the turns ratio. 2 Since Z 2 = V 2 ÷ I 2 and Z 1 = V 1 ÷ I 1 , Z 2 = N Z 1 .
