Title: Control circuit of power factor corrector
Inventor: CHEN CHENG-SUNG
IPC: G05F1/70
Filed: 2008-11-11
Abstract: The present invention relates to a control circuit, which is applied to a power factor corrector. An AC input voltage is rectified and converted by the power factor corrector into a rectified voltage. The control circuit outputs a switching signal to control a power switch. The control circuit includes a voltage-dividing filter circuit for generating an effective value voltage signal and an input current signal according to the rectified voltage that has been voltage-divided and filtered. The input current signal has a waveform that is the same as that of the rectified voltage, and a DC level is increased. A gain modulating circuit generates a control signal according to the input current signal, the effective value voltage signal and an error signal. The error signal is produced by an output end of the power factor corrector. Further, a switching circuit is coupled to the gain modulating circuit for outputting the switching signal based on the control signal and a saw-tooth signal, wherein the input current signal with a DC level is employed to add a working cycle into the switching signal at a zero point of an input inductive current, thereby increasing the power factor and decreasing the total harmonics distortion.
