Title:
ROTATING MACHINE CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/085177
Kind Code:
A1
Abstract:
A rotating machine control device (10) is capable of driving a multi-phase rotating machine (800) and a plurality of direct-current rotating machines (710, 720). First terminals (T1) which are one ends of the plurality of direct-current rotating machines (710, 720) are connected to a phase current path of one identical phase of a multi-phase winding set (801). A multi-phase power converter (601) converts a direct-current power of a power supply (Bt1) to a multi-phase alternating-current power, and applies voltages to the respective phase windings of the multi-phase winding set (801). Direct-current rotating machine switches (MU1H/L, MU2H/L) are composed of high potential-side and low potential-side switches connected in series via direct-current motor terminals (M1, M2). The direct-current motor terminals (M1, M2) are connected to second terminals (T2) of the direct-current rotating machines (710, 720). The direct-current rotating machine switches (MU1H/L, MU2H/L) make the voltages (Vm1, Vm2) of the direct-current motor terminals (M1, M2) variable by switching.
