In an aspect of the disclosure, an apparatus for wirelessly transmitting power is provided. The apparatus includes a communication circuit configured to communicate with a first wireless power transmitter and a second wireless power transmitter. The apparatus further includes a controller circuit configured to identify a first phase of a first current provided to the first wireless power transmitter, the first current generating a first magnetic field. The controller circuit further determines a time to provide a second current to the second wireless power transmitter. The controller circuit further provides the second current at the determined time with a second phase having a phase difference between the first phase configured to reduce a magnitude of a combined magnetic field of the first and second magnetic fields in a region between the first and second wireless power transmitters.
