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 (1) includes: a step-up type DC/DC converter circuit (11) for boosting voltage appearing at an output of the power storage part (C1) connected with a DC link; and a DC/AC conversion circuit (12, 14) for converting the boosted DC electric power into AC electric power and feeding it to an electric power source.
