Title:
PULSE PATTERN GENERATING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/208408
Kind Code:
A1
Abstract:
This pulse pattern generating device comprises: a line voltage imparting unit that imparts line voltage to a coil of a motor; and an induced voltage imparting unit that imparts induced voltage to a coil of the motor. The pulse pattern generating device comprises: a current calculation unit that calculates a current i which flows when the line voltage and the induced voltage are imparted to a coil; and a current effective-value calculation unit that calculates a current effective-value Irms from the current i. The pulse pattern generating device is provided with a pattern generating unit. The pattern generating unit generates a pulse pattern based on the current effective-value Irms.
