Abstract
Converter circuitry for a wireless power system is disclosed. The converter circuitry includes first and second switch legs each comprising two switches, wherein each switch is configured to transition between an on state and an off state. A controller is configured to control the states of the switches by alternating between a first switch sequence and a second switch sequence, wherein the controller successively alternates between the first switch sequence and the second switch sequence during a conversion period. The first switch sequence defines a first pattern of on states of the first, second, third, and fourth switches of the first and second legs, and the second switch sequence defines a second pattern of on states of the first, second, third, and fourth switches, wherein the second pattern is different than the first pattern.
