PROBLEM TO BE SOLVED: To reduce current nonequilibrium of respective conversion circuit modules in a power conversion apparatus in which a plurality of conversion circuit modules are connected in parallel.SOLUTION: The power conversion apparatus constituted of a plurality of conversion circuit modules connected in parallel includes: a first wiring for connecting a positive electrode terminal in a first conversion circuit module out of the conversion circuit modules to the positive electrode side of a DC wiring for supplying a DC current to the first conversion circuit module; and a second wiring for connecting a negative electrode terminal in a second conversion circuit module different from the first conversion circuit module out of the conversion circuit modules to the negative electrode side of the DC wiring for supplying a DC current to the second conversion circuit module. When a DC current flows into the power conversion apparatus, the first wiring and the second wiring are arranged so that magnetic coupling is generated between the first wiring and the second wiring.SELECTED DRAWING: Figure 1 |
