Abstract
A resonance system is disclosed, which includes a first resonance device configured to receive a drive signal and generate an output signal, a second resonance device configured to receive a control signal and generate the drive signal based on the received control signal, and a controller configured to generate the control signal based on the output signal such that a phase difference between the control signal applied to the second resonance device and the output signal of the first resonance device corresponds to a predetermined phase shift value.
