Abstract
(EN)
A driving device (20) for a rotary electrical machine includes: a first inverter (22) that is provided with a plurality of first switching elements (24-34) that correspond to respective phases of the rotary electrical machine (10) including multi-phase winding wires (12, 14, 16) and capable of forming/breaking connection between a first high potential point and one end of the corresponding winding wire and connection between one end of the corresponding winding wire and a first low potential point; a second inverter (36) that is provided with a plurality of second switching elements (38-48) having on-resistances lower than those of the first switching elements and capable of forming/breaking connection between a second high potential point and the other end of the corresponding winding wire and connection between the other end of the corresponding winding wire and a second low potential point; and a control unit (60) that turns the first switching elements on/off at a switching frequency higher than the electrical basic frequency of the rotary electrical machine, and turns the second switching elements on/off at a switching frequency lower than that of the first switching elements.
