Title:
POWER CONVERSION DEVICE, DRIVE DEVICE, AND POWER STEERING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/159835
Kind Code:
A1
Abstract:
This power conversion device converts power from a power source to power that is supplied to a motor provided with phase windings each having a first winding portion and a second winding portion connected together in series, and is equipped with: a first inverter that applies a drive voltage to one end of the first winding portions; a second inverter that applies a drive voltage to one end of the second winding portions; a neutral-point mechanism that connects the phase windings at any site between the other end of the first winding portions and the other end of the second winding portions; and a control unit that controls the drive voltages from the first inverter and the second inverter to a drive voltage at which the electric potentials of the phase windings at the sites where the phase windings are connected to the neutral-point mechanism reach the same electric potential.
