Title:
VOLTAGE CONVERSION CONTROL DEVICE FOR MOTOR
Document Type and Number:
WIPO Patent Application WO/2012/077203
Kind Code:
A1
Abstract:
Provided is a control device (18) that controls voltage conversion with respect to a voltage conversion circuit (12) between a power supply (10) and motor control circuits (14, 15) that control multiple motors (16, 17). The control device is characterized by being equipped with: sampling means (13a, 18m) that sample the current-voltage after voltage conversion; target voltage setting means (18e, 18f) that set the target voltages VHT1, VHT2 for the multiple motors (16, 17); a selection means (18j) that selects, from the multiple target voltages VHT1, VHT2, the target voltage VHT converted in the voltage conversion circuit (12); a generating means (18k) that generates a sampling timing TS on the basis of a carrier signal for one of the motors having the target voltage that was not selected; and control means (18g, 18l) that, for each voltage conversion control sampling timing request DS, control the voltage conversion using the current-voltage sampled by the sampling means (13a, 18m) in response to the sampling timing TS.
