Zusammenfassung:	To provide a power conversion circuit capable of supplying electric power from an AC power source to a DC power source and regenerating electric power from a DC power source to an AC power source or a load.SOLUTION: A power conversion circuit according to one aspect of the present invention includes a high frequency transformer, a bridge leg arranged on a primary side, a DC capacitor, and a full-bridge circuit arranged on a secondary side. The bridge leg includes a first leg, a second leg, and a third leg, and is arranged with six active switches. The full-bridge circuit includes a first leg and a second leg, and is arranged with four active switches. The full-bridge circuit is configured to be connected in parallel with a DC power supply.SELECTED DRAWING: Figure 1 【課題】交流電源から直流電源への電力の供給及び直流電源から交流電源又は負荷への電力の回生が可能な電力変換回路を提供する。【解決手段】本発明の一側面に係る電力変換回路は、高周波トランス、１次側に配置されるブリッジレッグ、直流キャパシタ、及び２次側に配置されるフルブリッジ回路を備える。ブリッジレッグは、第１レッグ、第２レッグ、及び第３レッグを備え、６つのアクティブスイッチが配置される。フルブリッジ回路は、第１レッグ及び第２レッグを備え、４つのアクティブスイッチが配置される。フルブリッジ回路は、直流電源に並列に接続するように構成される。【選択図】図１
