Patent ID: 8344715

Claim:
A system for providing frequency control to a power converter, the system comprising: a controller configured to receive a load signal and generate a first control signal, the load signal indicating an output load for a power converter; and a signal generator configured to receive the first control signal and generate at least a first output signal; wherein: 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; the signal generator is further configured to generate a second output signal associated with a second signal strength and a second frequency; the second frequency is inversely proportional to a fourth time period and a fifth time period; and the second signal strength during the fourth time period is different from the second signal strength during the fifth time period.
