PROBLEM TO BE SOLVED: To provide a power conversion device equipped with a transformer or reactor core mounting structure, capable of reducing risk in which impact sheet is rubbed by the corner of the core and broken, and capable of securing sufficient resistance with respect to vibration or impact.SOLUTION: A transformer or reactor core 1 is pressed by a spring member 4 via an impact sheet 3 and mounted on a protrusion 2a formed on a base plate 2. In the protrusion 2a, a corner 2b therearound is rounded into an area smaller than that on the mounting surface of the core 1. Moreover, an elastic member 6 is fitted between the side surface of the core 1 and the spring member 4 and lateral displacement of the core 1 is prevented. 【課題】この発明は、コアの角で擦れて緩衝シートが破れるリスクを低減することができるとともに、振動あるいは衝撃に対する十分な耐性を確保できるトランスまたはリアクトルのコアの実装構造を備えた電力変換装置を提供することである。【解決手段】トランスまたはリアクトルのコア１がベースプレート２に形成された突出部２ａ上に緩衝シート３を介してバネ部材４によって押し付けられて実装されている。突出部２ａはコア１の実装面の面積よりも小さい面積で周囲の角部２ｂが丸められている。また、コア１の側面とバネ部材４との間には弾性部材６が装着されて、コア１の横ずれを防止している。【選択図】図１
