The transmitter coil plays a crucial role in reverse wireless charging. It is typically a coil of wire wrapped around a core material, such as ferrite or air. When an alternating current (AC) flows through the coil, it generates a magnetic field. The frequency and amplitude of the AC current determine the strength and frequency of the magnetic field.
In reverse wireless charging, the transmitter coil is designed to generate a magnetic field with a specific frequency and amplitude, allowing it to efficiently transmit power to the charging base. The coil is typically optimized for maximum power transfer, taking into account factors such as coil geometry, core material, and frequency.
The Role of the Receiver Coil
The receiver coil, located in the charging base, is designed to receive the electromagnetic field generated by the transmitter coil. It is typically a coil of wire wrapped around a core material, similar to the transmitter coil. When the receiver coil is exposed to the magnetic field, it induces an EMF, which is then converted into electrical energy.
The receiver coil is designed to be highly efficient, with a high quality factor (Q) and low resistance. This allows it to efficiently convert the magnetic field into electrical energy, minimizing energy losses.
