A power converter and an air conditioner having the same, in which the power converter includes a rectifying unit configured to rectify an input AC current and an interleave converter that has a plurality of converters and that is configured to convert rectified output from the rectifying unit to DC power and output the converted DC power. The power converter also includes a capacitor connected to an output terminal of the interleave converter, and a converter controller configured to control the interleave converter. The converter controller controls the interleave converter by calculating a load level of both terminals of the capacitor and changing a number of operating converters in the plurality of converters of the interleave converter based on the determined load level of both terminals of the capacitor.
