  • Patent number: 8901905
    Abstract: A method of generating spurious-noise-free power from a switching device. The method includes generating an oscillating signal in the form of a series of pulse trains, and randomly changing the switching frequency, or the on-time, or both the switching frequency and the on-time of the switching device. The method further includes causing the switching device to change from a first frequency to a second frequency only at the end of a pulse train of the first frequency, and causing the second frequency to start at the beginning of its first pulse train such that no switching duty-cycle disturbance at the time of the change from first to second frequency. In a particular embodiment, the method further generates spurious-noise-free power from a switching device by implementing a relationship between the different switching frequencies involved such that spurious-noise-free operation is achieved.
