Classification: CPC H  Y | IPC H

Claim 4:
5. A control method of a power converter, comprising:
providing a digital error signal through an error amplifying circuit;
when a controller receives a first external control command, providing a first working parameter corresponding to the first external control command through the controller, wherein the controller stores a plurality of working parameters;
generating a current digital compensation value according to the first working parameter and the digital error signal through a digital filter;
generating a pulse width modulation signal according to the current digital compensation value through a digital pulse width signal modulator;
when the controller receives a second external control command, providing a second working parameter corresponding to the second external control command through the controller;
calculating a transition value according to the second working parameter and the current digital compensation value through the controller; and
providing the second working parameter and the transition value to the digital filter through the controller,
wherein the controller comprises a decoder, a memory, and a computing unit, wherein the step of providing the second working parameter corresponding to the second external control command comprises:
receiving the second external control command through the decoder, and generating an indication signal according to the second external control command; and
choosing to output one of the working parameters as the second working parameter according to the indication signal through the memory,
wherein the step of calculating the transition value comprises:
calculating the transition value according to the second working parameter and the current digital compensation value through the computing unit.
