What are the main functions of power inductors
Compared with other inductors, inductors in general electronic circuits can only bear lower voltage through smaller current; The main characteristic of power inductor is winding with thick wire, which can withstand tens, hundreds, thousands, even tens of thousands of amperes.
When any inductor is electrified, it has a certain power, which is generally reactive power. If the DC resistance of the inductor wire is considered, it also consumes a certain amount of active power.
However, if the current passing through the inductor is much smaller than the current allowed by the wire, it is generally not called "power inductor". For example, the inductor of the radio receiving circuit can use the wire thickness as long as the loss is considered, and the current carrying capacity is not considered, so it is not a power inductor.
The so-called power inductors generally refer to those inductors with large current. In addition to the amount of inductance, the current through them should also be considered.
Power inductors are used in automotive electronics, disk drives of mobile phones, cameras, laptops and portable audio players.
The wide application of high-power conversion terminal components on the circuit board also leads to the increasing demand for high-efficiency DC converters and more sophisticated inductors.
