SPEED-SENSORLESS MOTOR CONTROL DEVICE AND METHOD FOR STARTING SPEED-SENSORLESS MOTOR |
摘要 |
A speed sensorless motor starting apparatus (100) for starting a motor includes a modular multilevel cascade inverter (1) of a double star chopper cell, a current command value creation unit (31) configured to create a current command value by using an amplitude command value and a frequency command value increased from 0 to a prescribed value over a predetermined period of time, and a motor start control unit (32) configured to start the motor by performing control so that a motor driving current output from the modular multilevel cascade inverter (1) to the motor can follow the current command value. |
