The present invention relates to a charging apparatus for an electric mobility. The charging apparatus according to an embodiment of the present invention comprises: a rectification unit for converting a power input from a power supply device from AC to DC; and a conversion unit for converting an output from the rectification unit according to a conversion ratio and outputting the converted output to a battery. The rectification includes a plurality of first switch elements connected in a bridge form. The conversion unit includes: a first rectification circuit including a plurality of second switch elements connected in the bridge form; a second rectification circuit including a plurality of third switch elements connected in the bridge form; and a conversion circuit connected between the first rectification circuit and the second rectification circuit, converting an input voltage according to the conversion ratio based on a turns ratio to output an output voltage. The second switch element comprises a high electron mobility transistor. An object of the present invention is to provide the charging apparatus capable of realizing a high power density.
