要約(日本語): Electronic devices such as smartphones and smart watches with built-in wireless charging functions have increased rapidly. This paper presents a method of recognizing the position on the receiving side by installing four coil sensors on the receiving side. Since this method does not require two-way communication with transmitter, there is no need to incorporate complex communication functions, and it is convenient because it can be designed only on the receiver side. The analysis results, assuming charging with a stand-type charger, show that when the transmitter/receiver coil diameter is 5 cm, even slight misalignments of up to 1 cm from the center can be recognized.
