What are the main aspects of power inductance? - Focus on microfluidic control technology

Compared with other inductors, the inductors in general electronic circuits can only withstand lower currents through smaller currents. The main feature of power inductors is that they are wound with thick wires and can withstand tens of amps, hundreds, and counts. Thousands, even tens of thousands of amps.
Any inductor has a certain power when it is energized. This power is generally reactive power. If the DC resistance of the inductor wire is considered, a certain amount of active power is also consumed during operation.
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”. For example, the inductance of the radio receiving loop can be considered as long as the loss is small, regardless of the current carrying capacity. inductance.
The so-called power inductors generally refer to those inductors with large currents. In addition to the inductance, the magnitude of the current is also considered.
Power inductors are used in automotive electronics, disk drives for mobile phones, cameras, laptops, and portable audio players.
The widespread use of high power conversion termination components on circuit boards has also led to an increase in the demand for high efficiency DC converters and finer inductors.
