An energy conversion device (10) comprises a reception antenna (101), a controller (102) and at least one energy conversion circuit (103); each energy conversion circuit is connected to both the reception antenna and the controller; when the reception antenna has received an electromagnetic wave of at least one frequency, the controller obtains, by means of the energy conversion circuit, the input power of the corresponding electromagnetic wave, then, on the basis of pre-stored correspondences among frequency, input power and standard impedance, obtains the standard impedance corresponding to the electromagnetic wave. Also disclosed are an energy conversion method and an additional energy conversion device. |
