Design of New Hollow Cylindrical Core for Collection of Magnetic Field Energy
Aiming at the characteristics of low power density,large mass and complex structure of the existing non-intrusive core,a new hollow cylindrical core with simple structure and integrated production is designed.Simulation re-sults show that its power density is inversely proportional to the shell thickness.In addition,an accurate power model of the hollow cylindrical core was established,which simplifies the design difficulty of the core.The core was made for ex-perimental verification.Under the same conditions,the mass of the hollow cylindrical core is reduced by 49%,and the power density is increased by 82%,which has good practical value and application prospect.
