Switchable inductor for strong currents |
摘要 |
Switchable inductors for strong currents are used especially in antenna tuning circuits. The value of the inductance between the terminals of the primary winding of an air-core static transformer is different depending on whether the secondary winding of the transformer is placed in an open circuit or in a short circuit by switching means formed by power semiconductor elements. Application in particular to antenna coupling circuits for VLF stations working by frequency hop transmission with highly selective antennas.
