Abstract: A method of reducing noise generated by pulse width modulation (PWM) signals includes generating a PWM pulse train using a first set of parameter values and modifying the PWM pulse train during a near-field communication so that the PWM pulse train is generated using a second set of parameter values. Modifying the PWM pulse train includes reducing at least one parameter value of the first set of parameter values. The method further includes resuming generation of the PWM pulse train using the first set of parameter values after the near-field communication.

Abstract: Control over the operation of an electrically-controlled motor is supported by an interface circuit between the electrically-controlled motor and a near-field radio frequency communication controller. The interface circuit includes a first circuit that receives at least one control set point through a near-field radio frequency communication issued by the near-field radio frequency communication controller. A second circuit of the interface generates one or more electric signals in pulse width modulation based on the control set point.
