Title:
ROTATING MACHINE CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/185381
Kind Code:
A1
Abstract:
Provided is a rotating machine control device capable of reducing the effective value of a bus AC component by taking advantage of flexibility that two sets of armature windings and two sets of inverters are provided, without the necessity of synchronizing the on/off-control timing of a first set of switching elements with the on/off-control timing of a second set of switching elements. The rotating machine control device (30) calculates a utilization rate setting command for changing a utilization rate ratio (R12) from 1 to 1 so that the effective value of the bus AC component, which overlaps the bus current flowing through a bus (7) connecting a DC power supply (5) and two sets of inverters (6a, 6b) to each other, becomes lower than that in the case where the utilization rate ratio (R12) between the voltage utilization rate of a first set and the voltage utilization rate of a second set is 1 to 1.
