Summary: | 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
【課題】複数の変換回路モジュールを並列接続した電力変換装置において、各変換回路モジュールの電流非平衡を軽減する。【解決手段】並列接続した複数の変換回路モジュールから構成される電力変換装置であって、変換回路モジュールのうち、第1の変換回路モジュールにおける正極端子と、第1の変換回路モジュールに直流電流を供給する直流配線の正極側とを接続する第1の配線と、変換回路モジュールのうち第1の変換回路モジュールとは異なる第2の変換器における負極端子と、第2の変換回路モジュールに直流電流を供給する直流配線の負極側とを接続する第2の配線と、を有し、電力変換装置に直流電流を流した場合に、第1の配線と第2の配線との間で磁気結合が生じるように、第1の配線および第2の配線が設けられている。【選択図】 図1 |
