摘要： System and method for protecting a power converter. The system includes a compensation system configured to receive an input signal and generate a control signal, a cycle threshold generator configured to receive the control signal and generate a cycle threshold, and a comparator configured to receive the cycle threshold and a feedback signal and generate a comparison signal. Additionally, the system includes a pulse-width-modulation generator configured to receive the comparison signal and generate a modulation signal in response to the comparison signal, and a switch configured to receive the modulation signal and control an input current for a power converter. The input current is associated with an output power for the power converter. The cycle threshold corresponds to a threshold power level for the output power. The threshold power level is constant, decreases, or increases with respect to the input signal.

摘要： 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.
