Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a power conversion device capable of suppressing increase in size.SOLUTION: An insulation type DC-DC converter comprises a pattern having a first pattern provided between an input terminal and a coil at a primary side, and a second pattern provided between an output terminal and a coil at a secondary side. A part of the pattern with a lower voltage of the primary side of a transformer and the secondary side of the transformer is configured by a metal plate, and the other part of the pattern is configured by a metal foil having a smaller cross sectional area than the metal plate. The metal plate is mounted on the pattern of a substrate 40 by solder.SELECTED DRAWING: Figure 10
【課題】大型化を抑制することができる電力変換装置を提供する。【解決手段】絶縁型DC−DCコンバータは、入力端子と一次側の巻線との間に設けられる第1のパターンと、出力端子と二次側の巻線との間に設けられる第2のパターンとを有するパターンと、を有する。トランスの一次側およびトランスの二次側のうち電圧が低い方におけるパターンの一部が金属板で構成されるとともに、パターンの他部が金属板より断面積が小さい金属箔で構成され、金属板は基板40のパターンに対して半田で実装されている。【選択図】図10 |
