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.
