The input current ripple reduction circuit of the power factor correction circuit

摘要

According to one aspect of the present invention, an input current ripple reduction circuit of a power factor correction circuit capable of reducing the cost of products comprises: a ripple reducing unit reducing ripple of a current through current reduction of rectified alternating current power so that the ripple of the rectified current of the supplied alternating current power may be reduced and transmitted to a switching element; and a noise filter condenser removing the ripple of the current reduced through the ripple reducing unit.
