Document Type and Number:
WIPO Patent Application WO/2024/042598
Kind Code:
A1
Abstract:
This motor driving device comprises a first inverter, a second inverter, a plurality of opening and closing connections, a plurality of semiconductor switch elements, and a controller. The controller, at the opening or closing of the opening and closing connections, executes a pseudo neutral point operation and turns on the semiconductor switch elements in advance. First wirings each have a first inductance, second wirings each have a second inductance, and third wirings each have a third inductance. The third inductance value is smaller than the total of the first inductance value and the second inductance value.
