Title:
ROTATING MACHINE CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/057449
Kind Code:
A1
Abstract:
This rotating machine control device (1) comprises: a voltage applicator (3) for generating a three-phase voltage to be applied to a rotating machine (2); and a controller (4) for controlling the voltage generation operation of the voltage applicator (3) with a first pulse width modulation mode, that is, a pulse width modulation mode in which a carrier wave frequency is not synchronized with the frequency of a voltage command, or with a second pulse width modulation mode, that is, a pulse width modulation mode in which the carrier wave frequency is synchronized with the frequency of the voltage command, wherein the controller (4) selects either the first pulse width modulation mode or the second pulse width modulation mode as a pulse width modulation mode to be used to control the voltage generation operation on the basis of a first carrier wave used to generate a signal for controlling the voltage applicator with the first pulse width modulation mode, a second carrier wave used to generate a signal for controlling the voltage applicator with the second pulse width modulation mode, and an output voltage phase command indicating a phase of an output voltage to the rotating machine.
