Title:
POWER CONVERSION DEVICE, MOTOR MODULE, AND ELECTRIC POWER STEERING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/053974
Kind Code:
A1
Abstract:
This power conversion device is provided with: an inverter connected to the other ends of n (n is an integer of 3 or more) phase windings; a first phase separation relay circuit for switching connection/non-connection between a power supply and the n phase windings with the inverter interposed therebetween on a per-phase basis; a sub-inverter having at least one leg connected in parallel with the n legs of the inverter and connected to a motor neutral point node N where one ends of the n phase windings are Y-connected and the other ends of the n phase windings; and a second phase separation relay circuit for switching connection/non-connection between the power supply and the n phase windings with the sub-inverter interposed therebetween and switching connection/non-connection between the power supply and the neutral point node.
