AI Technical Summary
Conventional inductors can only be used on one layer of a PCB and require connection to a second layer of PCB via cables or copper busbars, resulting in low space utilization, time-consuming installation, and high costs.
The inductor structure uses a toroidal magnetic core wrapped around multiple coils. The coil output ends match the hollow columns of the upper and lower base plates and are directly connected to the upper and lower PCB boards through the upper and lower base plates, eliminating the need for additional connecting cables or copper busbars.
It achieves high space utilization and low-cost double-layer PCB installation, simplifying the installation process.
