Title:
CONDUCTOR CONNECTION STRUCTURE OF 5-LEVEL INVERTER
Document Type and Number:
Japanese Patent JP2018182869
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To connect an output of a DC portion 101 of a 5-level inverter and an input of an AC portion of each phase with a short conductor distance, and to reduce a size of a lamination direction of a conductor laminate.SOLUTION: Phase voltage output conductors 1, 2, and 3 of U-phase, V-phase, and W-phase are disposed in a center in the direction of a lamination so as not to be overlapped mutually, and on an outside thereof, a pair of neutral point potential conductors 4 and 5 are laminated. On the further outside thereof, a + side intermediate potential conductor 6 and a - side intermediate potential conductor 7 are laminated, and on the further outside thereof, a + side maximum potential conductor 8 and a - side maximum potential conductor 9 are laminated. A module of a DC portion 101 is disposed on one side in an x direction orthogonal to a lamination direction, and on the other side, a module of three AC portions is disposed, so that the output of the DC portion 101 and the input of the AC portion are connected with a short conductor distance. A potential difference between the phase voltage output conductors 1, 2, and 3 and the maximum potential conductors 8 and 9 is divided due to an interposition of the neutral point potential conductors 4 and 5.SELECTED DRAWING: Figure 2
