Abstract
How much power can be sent across coils powered by an AC power source is one of the most
frequent queries in the Wireless Power Transfer (WPT) technology. The topic of this study is how to find the
AC power supply frequency that maximizes WPT. It is practically crucial to identify the ideal frequency in a
few frequency trials, even if it is theoretically feasible to do so by using a broad range frequency sweep. A
frequency spotting method using a square wave input power signal is proposed in this research. With
knowledge of response by square wave input, the technique eliminates a lengthy and time-consuming
sweeping operation. On each data sample increment iteration, the Automatic Multiscale-based Peak Detection
(AMPD) method is used to choose the first peak discovery. This is followed by further analysis to determine
the set of peak patterns by computing error parameters.
