Abstract

System and method for providing frequency control to a power converter. The system includes a controller configured to receive a load signal and generate a first control signal. The load signal indicates an output load for a power converter. Additionally, the system includes a signal generator configured to receive the first control signal and generates at least a first output signal. The first output signal is associated with a first signal strength and a first frequency. The first frequency is inversely proportional to a sum of a first time period, a second time period, and a third time period. The first signal strength increases with the time during the first time period, the first signal strength decreases with the time during the second time period, and the first signal strength is constant with respect to the time during the third time period.
