Abstract
(EN)
This converting device for converting DC power from a plurality of DC power supplies into AC power and supplying the AC power to a load is provided with: a filter circuit including an AC reactor and a first capacitor; a DC/AC inverter connected to a load through the filter circuit; DC/DC converters provided between each of the plurality of DC power supplies and the DC/AC inverter; second capacitors provided between the DC/AC inverter and the DC/DC converters; and a control unit for setting each current target value of the DC/DC converters to be synchronized with a current of the AC power on the basis of a voltage of the AC power, a voltage change by a current flowing through the AC reactor and impedance, a reactive current flowing through each of the first and second capacitors, and a voltage of each DC power.
