Abstract
Transferring wireless power using a multiple pulse width modulation M-PWM driver signal includes generating the multiple PWM driver signal such that the pulse width varies in accordance with the magnitude of a periodic modulating curve. The M-PWM driver signal adjacent a zero-crossing of the periodic modulating wave is modified by reducing an interval between the zero-crossing and at least one pulse of the M-PWM driver signal closest to the zero-crossing. The modified M-PWM driver signal is used to open and close a switch in a wireless power transfer charging circuit.
