摘要:
A wireless power enabled apparatus includes a wireless power receiver. The wireless power receiver includes one or more receive coils configured to generate an AC power signal responsive to a wireless power signal. The wireless power receiver also includes two or more inductors configured with tightly coupled windings that share a common leakage inductance. Switching circuits are included such that each switching circuit is operably coupled to a corresponding one of the inductors. Control logic is configured to operate switches of the switching circuits such that each of the switching circuits and its corresponding two or more inductors are operated to shift between an energy storage mode for one or more phases of a switching period and an energy transfer mode for other phases of the switching period and the phases combine to comprise an entirety of the switching period.
