Abstract
A power converting apparatus is configured with single-phase sub-converters () connected to AC input lines of individual phases of a three-phase main converter () in series therewith. In a control device () for performing output control of the power converting apparatus, a current command value calculating circuit () which adjusts a DC voltage command given to the main converter () so that DC voltages of the sub-converters () follow a command and generates AC current commands so that a DC voltage of the main converter () follows the DC voltage command is configured with a CPU, and AC currents are controlled by switching output voltage levels of the sub-converters () at an AC side thereof so that deviations of instantaneous AC current values from the AC current commands become smaller.
