Abstract
A local coil may include: a wireless power receiver, for converting electrical energy to AC electricity, the electrical energy being wirelessly received from a power source; an AC-DC converter, for converting the AC electricity to first DC electricity having a first voltage; a DC-DC converter, for converting the first DC electricity to second DC electricity having a second voltage; a comparator, for comparing the first voltage and the second voltage, and generating a level signal on the basis of a comparison result; and a transmitter, for sending the level signal to the power source, such that the power source adjusts an output power of the electrical energy on the basis of the level signal. The wirelessly supplying of power to a local coil as well as power feedback control is achieved to advantageously increase energy transmission efficiency and system robustness.
