1. Energy storage and conversion:
Inductors are widely used in transformers and switching power supplies, and can efficiently store and convert electrical energy. Transformers use inductors to transmit and convert energy to meet different voltage requirements.
2. Filters:
In filter circuits, inductors are used in conjunction with capacitors to form low-pass, high-pass or band-pass filters, which can effectively filter signals of specific frequencies and purify power or signals.
3. Signal tuning:
In radio and television receivers, inductors and capacitors together form a resonant circuit, which can selectively amplify signals of specific frequencies and improve reception quality.
4. Current limiting and protection:
Inductors can be used as current limiting elements to prevent excessive current from damaging other circuit components. Its reverse electromotive force can protect the circuit in overload conditions.
5. Magnetic field applications:
Inductors can also be used to generate magnetic fields, such as in devices such as motors, relays and sensors, to achieve specific magnetic field effects by controlling current.
