Provided are a charging/discharging power-converting apparatus and a method for controlling same. The charging/discharging power-converting apparatus according to one embodiment of the present invention comprises: an inverter connected to a system to perform DC-AC conversion; a converter connected to a battery to perform DC-DC conversion; and a DC link interposed between the inverter and the converter. Resonance is generated by the elements arranged in the converter. Thus, resonance is generated by the elements arranged in the DC-DC converter, and therefore ZVS and ZCS can be performed without an additional resonant tank, thus reducing losses caused by on/off switching. Further, charging current can be controlled to constant current without an additional resonant tank by monitoring the current of a DC link, thus enabling a battery to be quickly charged.
