Abstract
A control circuit of a power converter including a first and a second control modules is provided. The first control module sets sampling points for a ripple signal of an input voltage according to a reference signal. The first control module determines whether a power point is the maximum power point according to ripple voltages of the sampling points. The second control module controls the power converter to output a maximum power according to the maximum power point based on the determination result of the first control module and the reference signal. An embodiment of a method for tracking a maximum power point is provided. The input voltage of the power converter is measured. The sampling points are set for the ripple signal of the input voltage and phase information of the ripple signal is determined, such that the maximum power point is determined by using the ripple voltages.
