Abstract
The present invention is directed to the provision of a servomotor driving apparatus that feeds energy stored in a power storage part connected with a DC link that connects a rectifier circuit with an inverter circuit so that the energy stored in the power storage part can be reduced. A motor driving apparatus () includes: a step-up type DC/DC converter circuit () for boosting voltage appearing at an output of the power storage part (C) connected with a DC link; and a DC/AC conversion circuit () for converting the boosted DC electric power into AC electric power and feeding it to an electric power source.
