Medical inductor coil is a wireless charging coil used in medical equipment products, including devices, instruments, large equipment, etc. Medical coils, also known as large-sized coils or flat coils, are a type of wireless charging that utilizes the principle of near-field electromagnetic induction to transfer energy from the charging dock (pad) to portable devices. When changing the distance, the wireless charging coil (Tx) in the charging dock transfers energy to the receiver coil (Rx) embedded in portable devices such as mobile phones. The transmitter/primary coil in the charging dock generates an electromagnetic field similar to a traditional transformer when powered on, inducing current to flow through the secondary coil on the portable device. The charging base has a power conversion circuit that converts electrical energy into an electromagnetic field. At the receiver, the power pickup unit converts the electromagnetic field back into electrical energy to charge the device's battery. The transmitter and receiver communicate with each other to control the charging process.
