Wireless Charger Electromagnetic Shielding Filters

The patent applies electromagnetic shielding filters that convert harmful electromagnetic waves into beneficial effects by absorbing or reflecting the waves in controlled directions. The shielding filters transform the harmful EMI and harmonic signals into manageable electromagnetic fields that can be directed away from sensitive devices, thus converting the harmful radiation into a controlled electromagnetic environment.

The electromagnetic shielding filters serve as intermediary elements positioned between the transmitting coil and surrounding devices. These filters act as mediators that intercept electromagnetic waves before they reach sensitive equipment, absorbing or redirecting the harmful radiation while allowing the wireless power transmission function to continue operating at high power levels.

The patent implements electromagnetic shielding filters at specific locations around the transmitting coil where electromagnetic interference is most problematic. Rather than applying uniform shielding throughout the entire system, the filters are strategically positioned in areas where EMI affects surrounding devices, thus locally reducing interference while maintaining charging efficiency in the primary transmission zone.

The patent applies electromagnetic shielding filters selectively to specific regions where interference is problematic, rather than implementing complete shielding around the entire transmitting coil. This partial action approach reduces EMI in critical areas while avoiding excessive shielding that would impede the wireless power transmission and reduce charging efficiency.
