Claim Text:
1. A control circuit of a power converter, the control circuit comprising: a first control module, setting a plurality of sampling points for a ripple signal of an input voltage of the power converter according to a reference signal, determining phase information of the ripple signal, and determining whether a power point of an energy generating system is a maximum power point according to a plurality of ripple voltages corresponding to the sampling points; and a second control module, electrically connected to the first control module, and controlling the power converter to output a maximum power according to the maximum power point based on a determination result of the first control module and the reference signal, wherein the ripple voltages comprise a first ripple voltage and a second ripple voltage, and when the first ripple voltage is equal to the second ripple voltage, the first control module determines the power point of the energy generating system to be the maximum power point.
