The objective of the invention is to reduce the impacts of transient currents generated when a modulation scheme is switched. When this rotating electrical machine control device (2), which switches a modulation scheme in accordance with operating conditions including, at least, a speed of rotation (ω) of a rotating electrical machine (80), switches the modulation scheme between asynchronous modulation (ASYNC_MOD) in which a modulation pulse is generated on the basis of a carrier having a first carrier frequency (cf1) that is not synchronized to the rotation of the rotating electrical machine (80) and synchronous modulation (SYNC_MOD) in which a modulation pulse is generated in synchronism with the rotation of the rotating electrical machine (80), the modulation scheme is switched by way of high-frequency asynchronous modulation (HF_ASYNC_MOD) in which a modulation pulse is generated on the basis of a second carrier frequency (cf2) having a higher frequency than the first carrier frequency (cf1). |
