The present invention relates to a power factor correction circuit of an interactive way. The power factor correction circuit of the present invention includes: a main switch unit which includes a first main switch and a second main switch which control a phase difference of the current and voltage of input power by a switching operation; a main inductor unit which includes a first main inductor and a second main inductor which accumulate or emit energy by each switching of the main switch and the second main switch; a snubber switch unit which includes a first snubber switch and a second snubber switch which provide the zero voltage turn-on condition of each of the first and second main switches; and a control unit which controls the switching operation of the main switch unit and the snubber switch unit. The control unit is able to control at least one group of: a first group which is set as the first main switch and the first snubber switch according to currents which flow in the main inductor unit; and a second group which is set as the second main switch and the second snubber switch.
