Some KNOWLEDGE ABOUT High current inductors
The high current inductor is an inductor which forms with a big size flat wire coil and magnet components, which is used high current requirement like automotive, new energy, power adapter, audio application…

In the high-frequency state, the current is concentrated on the surface of the copper wire. The closer to the surface of the copper wire, the greater the current density. The higher the frequency, the shallower the skin depth, and the middle position of the round copper wire cannot be used reasonably. With flat coil, flat copper wire of appropriate thickness can be selected according to different frequencies, which can maximize the utilization of copper wire cross-section. The utilization ratio of copper wire cross-section is the largest
