Abstract
Disclosed herein is an alternating current linked power converting apparatus, including: a direct current power unit including a plurality of cells, which provide a direct current (DC) voltage and are connected in series, wherein the direct current power unit has both ends connected to an inverter which converts the direct current voltage to an alternating current (AC) voltage; a cell balancing charger/discharger connected to the plurality of cells and balancing the direct current voltage or an amount of charging between the plurality of cells; and a ripple removing capacitor that is positioned between the cell balancing charger/discharger and the inverter and that includes a first terminal and a second terminal that are respectively connected to a first output terminal and a second output terminal of the cell balancing charger/discharger so as to remove ripples of the direct current voltage.
