What is the function of power inductor?

Overview of power inductance:

Power inductance is a simple energy storage element, which refers to the function of inductance. The greater the inductance, the smaller the power. On the contrary, the output current will go up when the inductance is reduced, including patch power inductance and plug-in power inductance from the perspective of circuit assembly. Such as magnetic ring inductance, hollow inductance, I-shaped inductance, patch winding inductance, patch shielding inductance, etc .. The high-power inductors used in electrical engineering are mainly composed of magnetic cores and copper wires. Compared with other inductors, power inductors can only pass a small current and bear a low voltage in general electronic circuits. The primary feature of power inductors is that they are wound with thick wires to withstand tens of amperes, hundreds, thousands or even tens of thousands of amperes. When any inductor is energized, it has a certain power, which is generally reactive power, assuming that it also consumes a certain amount of active power when considering the DC operation of the inductor wire; However, if the current passing through the inductor is much smaller than the current allowed by the conductor, it is generally not called "power inductor", such as the inductance of the receiving loop of a radio. Only the loss can be considered when using the wire thickness, regardless of the current carrying capacity, so it is not a power inductor. The so-called power inductors generally refer to those with large current, and besides inductors, the passing current should also be considered. Dongguan Xinyong Electronic Technology Co., Ltd. specializes in producing power inductors, which are developed to meet the needs of environmental protection. In the circuit, it mainly plays the role of choking and filtering, which is common in DC/DC converters. It has the characteristics of high power, high magnetic fullness and low impedance.

Power inductor application:

The wide application of high-power conversion terminal components on car electronics, mobile phones, cameras, notebook computer disk drives and portable audio players and circuit boards also increases the need for high-efficiency DC converters and finer inductors. In order to meet the challenge of habit, component manufacturers spend a lot of money on information and production to develop, produce and improve power devices, and meet the needs of the market with balanced or very good functions but increasingly detailed planning.
