Document Type and Number:
Japanese Patent JP7292516
Kind Code:
B2
Abstract:
This motor driving device (100) has first and second switching modes which are selected on the basis of mode selection information when a motor (1) is driven by inverters (3a, 3b). In the first switching mode, on/off timings of the respective switching elements in identical phases in the inverters (3a, 3b) are matched between the inverters (3a, 3b), and a switching operation is performed for each of the inverters (3a, 3b). In the second switching mode, on/off timings of the respective switching elements in identical phases in the inverters (3a, 3b) are made different between the inverters (3a, 3b), and the switching operation is performed for each of the inverters (3a, 3b).
