  • Push-pull driver for generating a signal for wireless power transfer
    Patent number: 9093215
    Abstract: This disclosure provides systems, methods, and apparatus for transferring power wirelessly via a wireless power transmitter. In one aspect, the transmitter comprises a first circuit configured to generate a first signal, where the first circuit includes a first inductor. The transmitter further comprises a second circuit configured to generate a second signal out of phase with the first signal. The second circuit includes a second inductor inductively coupled with the first inductor. The first inductor and the second inductor may have a leakage inductance of at least a minimum value so as to not produce a substantially square waveform at an output of the first circuit and an output of the second circuit. The transmitter further comprises a filter circuit configured to filter the first signal and the second signal.
