There is provided a power converter device in which a current is divided to flow in a plurality of semiconductor elements and a voltage drop is compensated so as to obtain an output voltage with high accuracy. In a power converter device wherein a leg (21) comprises two semiconductor device groups which are connected in series and a division current is generated in a current which flows in the semiconductor device group between elements in the semiconductor device groups, a current sensor (26) which detects a current which flows in the semiconductor device group, a voltage command generation unit (31) which calculates a voltage command value to be output, a voltage drop calculating unit (32) which calculates a voltage drop of the semiconductor device group by using a current value which is detected by the current sensor (26) and voltage drop characteristics including a division characteristic of the semiconductor device group and a switching control unit (33) which corrects a voltage command value which is generated by the voltage command generation unit by using the voltage drop which is calculated so as to control ON/OFF of the switching element are provided. |
