Title:
ROTATING ELECTRIC MACHINE CONTROL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/196719
Kind Code:
A1
Abstract:
A rotating electrical machine control system (100) for controlling an alternating current rotating electrical machine (80) provided with M coil sets (8) is provided with: M inverters (50) which are provided with a plurality of switching elements (5), are connected to a direct-current power source (41) and to each of the coil sets (8), and which convert electric power between direct current and an N-phase alternating current; M groups of current sensors (6), of which one group is provided for each coil set (8), and which detect the alternating current in each phase flowing through each coil set (8); and an inverter control device (30) for generating switching control signals (S) for controlling the plurality of switching elements (5). The inverter control device (30) uses all the detected values from the M groups of current sensors (6) for each of the N phases to perform current feedback control of the rotating electrical machine (80), and generates the switching control signals (S) common to the M inverters (50).
