Title:
SPEED-SENSORLESS MOTOR CONTROL DEVICE AND METHOD FOR STARTING SPEED-SENSORLESS MOTOR
Document Type and Number:
WIPO Patent Application WO/2014/133026
Kind Code:
A1
Abstract:
A speed-sensorless motor starting device (100) for starting a motor, provided with: a modular multilevel cascade inverter (1) of the double star chopper cell type; a current-command-value generation means (31) for generating a current command value using an amplitude command value, and a frequency command value that increases from 0 to a prescribed value during a prescribed amount of time; and a motor start control means (32) for starting a motor by performing control so that a motor drive current that is output from the modular multilevel cascade inverter (1) to the motor follows the current command value.
