Abstract
A power conversion unit includes a plurality of arms each having a plurality of converter cells connected to each other in cascade. A converter control unit that controls the power conversion unit includes a voltage command value computing unit to compute an output voltage command value for each arm, and a gate signal generating unit to generate an on/off control signal of each switching element of each converter cell in accordance with the output voltage command value. A voltage command value computing unit is configured to generate the output voltage command value with compensation for an AC vibration component, extracted for each arm, of stored energy of power storage elements of a plurality of converter cells included in the arm.
