System and method for controlling variations of switching frequency

Abstract

System and method for providing frequency control to a power converter. The system includes a pseudorandom signal generator configured to generate a digital signal. The digital signal is associated with at least an N-bit datum, and N is a positive integer. Additionally, the system includes a digital-to-analog converter configured to receive the digital signal and generate a first control signal, an output signal generator configured to receive the first control signal and generate at least a first output signal associated with a frequency, and a pulse-width-modulation generator configured to receive at least the first output signal. The N-bit datum represents a pseudorandom number.
