Document Type and Number:
WIPO Patent Application WO/2019/155918
Kind Code:
A1
Abstract:
The present invention reduces vibration of a motor. A power conversion device 100 according to an embodiment of the present invention converts power from a power source 101 to power to be supplied to a motor 10. The power conversion device 100 is provided with: a first inverter 110 which is connected to one end of a winding of each phase in the motor 10; a second inverter 140 which is connected to the other end of the winding of each phase; and a control circuit 300 which controls operations of the first and second inverters 110, 140. The control circuit 300 controls the 6-order component of a radial force acting on teeth 23 of a stator 20, on the basis of the 3-order component of the magnetic flux of permanent magnets 32 of a rotor 30 and the 3-order component of current to be supplied to the winding of an A phase.
