Title:
POWER CONVERSION DEVICE, MOTOR MODULE, AND ELECTRIC POWER STEERING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/026492
Kind Code:
A1
Abstract:
A power conversion device, provided with: a first inverter 100A; a second inverter 100B; a first control circuit and second control circuit 410A, 410B for controlling the first and second inverters; and a drive circuit 440 for supplying a control signal for switching on a low-side switch element of the first inverter to the low-side switch element when a fault occurs on the first inverter side, and supplying a control signal for switching on a low-side switch element of the second inverter to the low-side switch element when a fault occurs on the second inverter side. When a fault occurs on the second inverter side, a first power supply voltage generated on the first inverter side is fed to the drive circuit, and when a fault occurs on the first inverter side, a second power supply voltage generated on the second inverter side is fed to the drive circuit.
