Continuously adjustable inductance e.g. for fine tuning of resonant circuits, is formed between connection terminals of main winding, and second legs of O-shaped cores are each enclosed by short circuit winding
Continuously adjustable inductance e.g. for fine tuning of resonant circuits, is formed between connection terminals of main winding, and second legs of O-shaped cores are each enclosed by short circuit winding
The device has two O-shaped cores in the main circuit with a main winding (10,11) on the first legs (3,4), a common auxiliary winding (12) on the second legs (5,6) and an air gap (9) between the second legs. The auxiliary winding is supplied with a direct current of definable amplitude and the inductance is formed between the connection terminals of the main winding. The second legs are each enclosed by a short circuit winding (13,14).
