In general, the shape, wire diameter, Q, inductance, and core are all the same. They are also theoretically interchangeable because they are essentially the same.
Transformers and inductors both have coil windings, but they have different structures and functions. Transformers must have at least one tap or two windings, and using different taps or windings to convert AC circuits also affects the inductance. An inductor is a double-ended device with only one tap for storing energy and converting phase. Wireless signals are converted to current signals by coils wound in space, also known as induction coils.
The main function of a transformer is to convert high-voltage alternating current to low-voltage alternating current. The main function of an inductor is to isolate and filter AC signals or to form a resonant circuit with capacitors and resistors.
The voltages generated are as follows: 1) the inductive reactance of the inductor resonates with the alternating current, but does not affect the direct current; 2) the transformer generates a voltage by mutual inductance through its inductance on the secondary side.
Differences in the method of connection: 1) transformer in the circuit in parallel with the AC power supply; 2) although the inductance has a blocking effect on the AC, but does not completely block the current through the circuit.
There are differences in the effect of AC: 1) Since AC is limited by inductive reactance, inductance is the limiting factor; 2) Transformers work as AC loads, they convert energy rather than transfer it.
The main applications of transformers are LED lighting, converter technology for commercial and medical purposes, high voltage, and electrostatic spraying. Inductors are widely used in smartphones, automobiles, computers, televisions, and smartwatches.
