Abstract
In a converter device comprising smoothing capacitors 2a, 2b connected in series and disposed at a DC output side, a voltage unbalance is produced between these smoothing capacitors in accordance with a current flowing through a connecting point Q of the smoothing capacitors 2a, 2b. The current flowing through the connecting point is detected and in response thereto a dummy resistor 10 is selectively connected in parallel with the smoothing capacitor 2a at the side where the load is not connected, thereby effectively eliminating the voltage unbalance with less power loss.
