Controller of power converter

A controller of a power converter, the controller providing a control signal to cause the power converter to generate an output voltage, the controller comprising:

• an error amplifier, coupled to the power converter and configured to generate an error signal according to the output voltage;
• a compensation circuit, coupled to the error amplifier and configured to generate a compensation signal according to the error signal, wherein the compensation circuit comprises a compensation resistor;
• a comparison circuit, coupled to the compensation circuit and configured to generate a trigger signal according to the compensation signal;
• an adjustment circuit, coupled to two terminals of the compensation resistor and configured to generate an adjustment signal according to a cross-voltage between the two terminals of the compensation resistor;
• and
• a control signal generation circuit, coupled to the comparison circuit and the adjustment circuit and configured to generate a control signal according to the trigger signal and adjustment signal.
