Abstract:
A power factor correction circuit can include: a power meter configured to measure THD at an input port; a switching-type regulator that is controllable by a switching control signal in order to adjust a power factor of an input signal thereof; and a controller configured to generate the switching control signal to control the switching-type regulator to perform power factor correction, where the controller minimizes the THD by adjusting a current reference signal according to a measured THD, and the current reference signal represents an expected inductor current of the switching-type regulator.

Claim (Index 13):
The method of  claim 9 , wherein said inversely superimposing comprises:\n a) multiplying at least one voltage harmonic component with a compensation signal respectively, wherein each voltage harmonic component corresponds to each harmonic component and has a corresponding amplitude; and b) inversely superimposing at least one signal obtained by the multiplication operation respectively on a product of an input voltage sampling signal and said compensation signal to generate said current reference signal, wherein said input voltage sampling signal is used to represent an input voltage of said switching-type regulator, said voltage harmonic component is obtained according to said input voltage sampling signal, and said compensation signal represents a difference between a voltage reference signal and said output voltage.
