Abstract
A two layer predictive controller for bidirectional inductive power transfer can include: a first layer controller generating a mutual inductance and a reference active power; and a second layer controller receiving the mutual inductance and the reference active power, and generating a primary phase shift, a secondary phase shift, and a differential phase shift; the primary phase shift configured to manage a magnitude of an output voltage of a primary inverter; the secondary phase shift configured to manage a magnitude of an output voltage of a secondary inverter; and the differential phase shift being a phase difference between the output voltage of the primary inverter and the output voltage of the secondary inverter.
