Apparatuses and related methods for detecting magnetic flux field characteristics with wireless power transmitter

A wireless power transmitter may include a transmit coil configured to generate a wireless power signal for wireless power transfer, at least one secondary sensing coil configured to generate a signal responsive to a magnetic flux field generated during the wireless power transfer, and control logic configured to detect at least one condition of a wireless power transfer system responsive to detecting distortion in the magnetic flux field from the at least one signal received from the secondary sensing coil. A related method may include generating with a wireless power transmitter a wireless power signal, generating with a plurality of secondary sensing coils one or more signals responsive to a magnetic flux field generated during the wireless power transfer, and detecting at least one condition of a wireless power transfer system responsive to the one or more signals generated by the plurality of secondary sensing coils. 无线电力发射机可以包括：发射线圈，被配置为产生无线电力信号以进行无线电力传输；至少一个次级感测线圈，被配置为响应于在所述无线电力传输期间产生的磁通量场产生信号；以及控制逻辑，被
