    摘要： There is provided a power factor correction circuit capable of correcting a power factor of a power converting module through increasing an input current by switching a main switching element of a power converting module on the basis of a first reference wave having a slope based on a first signal and an error voltage, in particular, by limiting a switching frequency on the basis of a first reference wave having a slope based on a second signal lower than a first signal and an error voltage when the switching frequency of the main switching element increases because an input voltage of the power converting module is low.

    摘要： A relaxation oscillator includes a ramp wave generator configured to generate a ramp wave by complementary first capacitor module charged and discharged according to a first switching signal and second capacitor module charged and discharged according to a second switching signal, a negative feedback circuit unit configured to generate a compensation voltage for compensating an error between the ramp wave and a reference voltage through a feedback of the ramp wave, and a switching signal generator configured to generate the first switching signal and the second switching signal from the compensation voltage and the ramp wave, including a peak voltage storage unit configured to store a peak voltage of the ramp wave that is controlled to be equal to the reference voltage based on the compensation voltage and a peak voltage transfer unit configured to transfer the peak voltage of the ramp wave to the negative feedback unit.
