電力変換装置、駆動装置およびパワーステアリング装置

Japanese Patent JP7342561

B2

The invention provides a power conversion device, a drive device, and a power steering device, which are capable of ensuring independent element arrangement of a power supply and easily suppressing impedance difference between phases. A power conversion device is used for converting power from a power source and supplying the converted power to a motor having an n-phase winding, n being an integer of 3 or more, includes: a first inverter connected to one end of the winding and having switching elements for each of the n phases; a second inverter connected to the other end opposite the one end and having switching elements for each of n phases; a substrate, wherein the first and second inverters are provided with switching elements of each of n phases and a common element which is arranged on at least one of a power supply terminal and a ground terminal provided to the switching elements of each phase on the substrate, and the substrate is divided into mounting regions for the first and second inverters. The switching elements and the common elements in the first and second inverters are distributed and mounted for the common elements and each phase at n + 1 locations arranged in a ring shape when viewed from a direction perpendicular to the substrate.
