1. A wireless power transceiver device, comprising:
an energy module;
a magnetic interfacing unit comprising at least one transceiver coil;
a controller coupled to the magnetic interfacing unit, and configured to:
receive a first parameter indicating a state of an external device,
determine, based at least in part on the first parameter, whether the external device is a power receiving device or a power transmitting device, and
generate one of a first control signal or a second control signal to control a bi-directional driver based, at least in part, on whether the external device is the power receiving device or the power transmitting device, and
provide the first control signal or the second control signal to the bi-directional driver; and
the bi-directional driver coupled to the magnetic interfacing unit and the controller, wherein the bi-directional driver includes a plurality of switches, the bi-directional driver configured to:
control a direction of power transfer between the external device and the energy module through the bi-directional driver based on a state of the plurality of switches associated with the first control signal and the second control signal,
obtain energy from the energy module and output an outgoing AC signal through the at least one transceiver coil when the controller generates the first control signal, and
receive an incoming AC signal through the at least one transceiver coil and output energy to the energy module when the controller generates the second control signal.
