Abstract
The invention is directed to the provision of a converter apparatus, an inverter apparatus, and a DC link voltage control method, wherein the upper limit value of the DC link voltage that rises due to regenerative energy occurring from a motor is set high, thereby increasing the regenerative energy to be stored in a DC link. The converter apparatus () comprises: a voltage detection part () for monitoring the DC link voltage occurring across the DC link (); and a charge stopping part () for stopping charging a power storage part (C) when the detected value of the DC link voltage exceeds a predetermined upper limit voltage as the motor () is decelerated.
