Abstract
Systems and methods for operating a wireless power transfer device are described. A circuit can generate a first signal that indicates a voltage at a node between a first high-side (HS) transistor and a first low-side (LS) transistor in a switching converter falling below ground. The circuit can delay a gate-source voltage of a second LS transistor in the switching converter to generate a second signal. The circuit can merge the first signal and the second signal to generate a third signal. A controller can use the third signal to trigger a rising edge of a command signal to turn on the first LS transistor at a specific time. The first LS transistor being turned on at the specific time reduces a diode conduction time of a body diode of the first LS transistor.
