Is There A Difference Between High Frequency Transformers And Inductors?
- Jul 27, 2017 -

The same point: The wire wrapped in enameled wire, internal core or core.

Different points: transformers are mainly used for voltage conversion, which is based on the law of electromagnetic induction. Inductance coils are generally used in electronic circuits, according to Lenz. The former generally has two or three windings, with primary windings and secondary windings, for the step-up transformer, the primary winding turns few line diameter is coarse, the secondary winding turns the number and the line diameter is fine, the step-down transformer is opposite, the primary turns several lines are fine, the secondary turns few lines diameter is thick, is widely used in various electrical appliances as the power supply use. Inductive coils are used in electronic circuits for two basic purposes:

1, with the capacitor resistor used for waveform generation circuit or frequency selection circuit,

2, it is used as a flat wave device in the circuit which has large current and large pulsation. There are many other occasions, such as fluorescent lamps in the ballast, mainly based on inductance coil at both ends of the current can not be mutated when the current rate of change is too fast to produce a very high reverse electromotive force of the principle made.
