Title:
DYNAMOELECTRIC MACHINE CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/039268
Kind Code:
A1
Abstract:
A control device (30) to be used in a system equipped with a dynamoelectric machine (10) having multi-phase winding groups (14, 15), and power inverter circuits (INV1, INV2) for applying a voltage to the winding groups by alternatingly turning on upper and lower arm switches (SUp1-SWp2, SUn1-SWn2). The control device is equipped with: an adjustment unit (32) for adjusting the pulse width, which is the on-operation interval of each of the upper and lower arm switches in one electrical angle cycle of the dynamoelectric machine; and operation units (33, 34) for turning the upper and lower arm switches on one at a time during one electrical angle cycle in a manner such that the on-operation interval of each of the upper and lower arm switches during one electrical angle cycle equals the adjusted pulse width set by the adjustment unit, while satisfying a first condition that there is no overlap in the on-operation intervals of the upper arm switches corresponding to each phase, and a second condition that there is no overlap in the on-operation intervals of the lower arm switches corresponding to each phase.
