Title:
POWER CONVERSION APPARATUS, MOTOR DRIVING UNIT, AND ELECTRIC POWER STEERING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2018/180237
Kind Code:
A1
Abstract:
This power conversion apparatus is provided with: a first inverter; a second inverter; and a switching circuit that has a first switch element and a second switch element, wherein, in a state where potentials at a first node on the high side and at a second node on the low side are set equal and potentials at one end of winding wires of two phases among winding wires of n phases (n is an integer of 2 or more) are set equal in the first inverter, the winding wires of two phases are energized by using two legs connected to the other end of the winding wires of the two phases among n legs of the second inverter while switching is performed in the first and second switch elements in the switching circuit at a prescribed duty ratio.
