  "textContent": "Disclosed are methods controllers, and inverters for wireless power transfer using a multiple pulse width modulation, M-PWM, driver signal. The methods comprise: generating the multiple PWM driver signal wherein the pulse width varies in accordance with the magnitude of a periodic modulating curve; modifying the M-PWM driver signal adjacent a zero-crossing of the periodic modulating wave, by reducing an interval between the zero-crossing and at least one pulse of the M-PWM driver signal closest to the zero-crossing; and using the modified M-PWM driver signal to open and close a switch in a wireless power transfer charging circuit.",
