Electric field coupled wireless charging, does not use a coil for electromagnetic induction, butDirectly through the high frequency electric field in the capacitor formed between the charging base and the electrical appliance to be charged, that is, the induction electric field generated by coupling two sets of asymmetric dipoles in the vertical direction to transmit power, this charging method has the advantages of low cost and low alignment requirements. But there are not many actual products.
Electromagnetic induction wireless charging, when the current of the power supply through the coil (wireless charger's power supply coil) will generate a magnetic field, other unenergized coil (mobile phone side of the electric coil) close to the magnetic field will generate current, charging the mobile phone. The advantages of wireless charging safety: no power contact design, can avoid the danger of electric shock.
The transmitting end is often multiple strands of silk-covered wire, multiple strands of thinner enameled wire or gauze wrapped wire wound inductors are used in relatively high frequency circuits, such as the magnetic antenna rod coil of the radio, the shortwave radio coil, the high frequency transformer coil of the liquid crystal display lighting circuit, etc., often use multiple strands of wire and wound.
