PROBLEM TO BE SOLVED: To provide a power conversion circuit which has a plurality of input/output ports and which can transmit power between the ports; and which can inhibit unnecessary power transmission by comparatively simple control.SOLUTION: A power conversion circuit comprises a plurality of substrates 20 on which formed are half-bridge circuits 26, and the ungapped cores 22 around each of which a first winding wire connected with the half-bridge circuit 26 on at least one end winds and gapped cores 24 around each of which a second winding wire connected with the half-bridge circuit 26 on at least one end winds, in which the ungapped cores and the gapped cores lie on either sides so as to sandwich the half-bridge circuits 26, and the substrates are stacked in such a manner that the ungapped cores and the gapped cores lie alternately on the right and left. The neighboring two half-bridge circuits in the stacking direction compose an isolated DC/DC converter or a non-isolated DC/DC converter.SELECTED DRAWING: Figure 7 【課題】複数の入出力ポートを有し、ポート間で電力伝送が可能であるとともに、比較的簡易な制御で不要な電力伝送を抑制し得る電力変換回路を提供する。【解決手段】ハーフブリッジ回路２６と、ハーフブリッジ回路２６を挟むように左右にそれぞれ形成される、ハーフブリッジ回路２６に少なくとも一端が接続された第１の巻線が巻回されたギャップ無しコア２２、及びハーフブリッジ回路２６に少なくとも一端が接続された第２の巻線が巻回されたギャップ有りコア２４とを有する基板２０が左右互い違いとなるように複数個積層される。積層方向に隣接する２つのハーフブリッジ回路間で絶縁型ＤＣ／ＤＣコンバータあるいは非絶縁型ＤＣ／ＤＣコンバータを構成する。【選択図】図７
