Abstract
A controller of a power converter includes a sample-and-hold unit and an adjustment unit, wherein the power converter is applied to a Universal Serial Bus power delivery adapter system. The sample-and-hold unit is used for sampling a voltage to generate a sampling voltage during each period of a gate control signal, wherein the sampling voltage corresponds to an output voltage of the power converter. The adjustment unit is coupled to the sample-and-hold unit for adjusting at least one of a frequency of the gate control signal, a current flowing through a primary side of the power converter, and a resistance of a compensation resistor of the controller according to the sampling voltage.
