Magnetic core: apply glue on the middle part of the shaft core-put the magnetic block and the shaft core into the mold and compact the shape-put the magnet into the mold-magnetic force detection (complete to be assembled)
SMD Magnetic core
The reason for the loss of the inductance core: the loss of the chip inductor core mainly comes from the core loss and the coil loss, and the amount of loss in these two aspects needs to be based on their different circuits Mode to make judgments. Among them, the core loss is mainly caused by the alternating magnetic field in the core material. The loss it generates is a function of the operating frequency and the total magnetic flux swing (ΔB), which will greatly reduce the effective conduction loss. Coil loss is the energy loss caused by the change of magnetic energy. It will reduce the strength of the magnetic field when the power inductor current drops. Ways to reduce the loss of the inductor core: 1. The core loss generated in the inductor core will decrease the allowable copper wire loss as the inductor core loss increases, and it will also bring the same inductance core material flux to a surge. Therefore, when the switching frequency rises above 500 kHz, the inductor core loss and winding AC loss can greatly reduce the allowable DC current in the inductor. 2. The loss of the inductor core in the coil is mainly manifested in the loss of the copper wire. Therefore, if you want to reduce the loss of the copper wire, you must reduce the loss of the inductor core when it rises, and continue until the losses are equal. The better situation is that the losses remain stable and equal at high frequencies and allow the output current to be obtained from the magnetic structure.
