Converter apparatus, inverter apparatus, and DC link voltage control method |
摘要 |
<p>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 (10) comprises: a voltage detection part (11) for monitoring the DC link voltage occurring across the DC link (30); and a charge stopping part (12) 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 (3) is decelerated.</p> |
