Title:
MOTOR VOLTAGE CONVERSION CONTROL APPARATUS
Document Type and Number:
WIPO Patent Application WO/2012/144002
Kind Code:
A1
Abstract:
A control apparatus (18) for performing a voltage conversion control for a voltage conversion circuit (12) between motor control circuits (14, 15) for controlling a plurality of motors (16, 17) and a power supply (10), characterized by being provided with: sampling means (13a, 18l, 18m) for sampling a direct-current voltage after voltage conversion; target voltage setting means (18e, 18f) for setting target voltages (VHT1, VHT2) of the plurality of motors (16, 17); a selecting means (18j) for selecting a target voltage (VHT) to be converted by the voltage conversion circuit (12) from among the plurality of target voltages (VHT1, VHT2); a generation means (18k) for generating a sampling timing (TS) on the basis of a gate signal (GS1 or GS2) of one of the motors of the target voltage that has not been selected; and a control means (18g) for performing a voltage conversion control by using the direct-current voltage sampled by the sampling means (13a, 18l, 18m) in accordance with the sampling timing (TS) for each sampling timing request (DS) for voltage conversion control.
