Abstract: An apparatus is provided in which electromagnetic field components generated by a transmitting coil is induced to other transmitting coils based on plurality of transmitting coils being driven for multiple wireless charging, for example, wirelessly charging two or more receivers to prevent degradation in performance of detecting a receiving coil and a foreign object during multiple wireless charging. According to the present disclosure, the receiving coil and foreign object detecting apparatus in multiple charging conditions using the plurality of transmitting coils includes an induced signal processor. The induced signal processor can control an amount of voltage and an operation frequency corresponding to the wireless charging coil and can detect a peak and can include a filter to thereby prevent interference of a signal induced from other neighboring transmitting coils.
