Electrical Excitation Method

IP Title

Summary

Multi-phase AC excitation technique is fundamental to the fabrication of charging platforms that support simultaneous charging of electronic devices. This invention aims to improve excitation techniques by introducing novel means of exciting a multi-layer planar winding structure. An excitation current is injected into the respective layers at different phase angles which should be out of phase with each other by regular intervals. Multiple electromagnetic fields will be created on the charging platform, generating flux lines that flow like water fountains.
