ROTATING ELECTRIC MACHINE CONTROL SYSTEM

Title:

ROTATING ELECTRIC MACHINE CONTROL SYSTEM

Document Type and Number:

WIPO Patent Application WO/2020/255988

Kind Code:

A1

Abstract:

This rotating electric machine control system 100 controls an AC rotating electric machine in which two N-phase coil sets (8) are disposed in the same stator core, the rotating electric machine control system being provided with: a first inverter (51); a second inverter (52); and an inverter control device (10) which individually controls two inverters (50) so that currents having different phases respectively flow through the two coil sets (80). The inverter control device (10) stops the second inverter (52), switch-controls the first inverter (510) to convert power between DC power and N-phase AC power, or switch-controls the two inverters (50) to convert power between DC power and 2N-phase AC power. A switching element (5) forming the first inverter (51) has a shorter transition time between an off state and an on state than a switching element (5) forming the second inverter (52), and thus switching loss is small.
