Abstract
A system includes at least two transmit coils. The system further comprises at least two transmit circuit units, a detection circuit, a communication module and a controller. The detection circuit is electrically connected to each of the transmit circuit units. The detection circuit and the communication module are both configured to acquire the coupling relationship between each of the transmit coils and a receive coil. The controller is electrically connected to the detection circuit, each of the transmit circuit units, and the communication module. The controller is configured to control, based on the acquired coupling relationship, the current output by each of the transmit circuit unit. The controller controls each of the transmit circuit units to supply a suitable current amplitude and a current phase to each of the transmit coils to achieve control of superimposed magnetic fields generated by currents on the transmit coils.
