Abstract

Systems and methods for wireless power transfer systems are described. A controller can be coupled to a power rectifier configured to rectify alternating current power into direct current power. The power rectifier can include a first high side transistor, a second high side transistor, a first low side transistor, and a second low side transistor. The controller can be configured to operate the power rectifier in full bridge rectifier mode. The controller can be further configured to detect a misfire event between the wireless power receiver and a wireless power transmitter. The controller can be further configured to, in response to detection of the misfire event, switch an operation mode of the power rectifier from the full bridge rectifier mode to a diode mode.
