PROBLEM TO BE SOLVED: To provide a coil structure having a robust structure and a power converter including the coil structure.SOLUTION: The coil structure includes: a bobbin structure wound with a primary winding; a first coil part formed with the primary winding; a second coil part that generates an induction current according to a current supplied to the first coil part; and an adjustment part that adjusts a leakage inductance by changing the direction of a magnetic flux generated by the current supplied across the first coil part and the second coil part. The bobbin structure holds the adjustment part. 【課題】頑健な構造を有するコイル構造体及び当該コイル構造体が組み込まれた電力変換装置を提供することを目的とする。【解決手段】本出願は、１次巻線が巻き付けられるボビン構造体と、前記１次巻線によって形成された第１コイル部と、前記第１コイル部への電流の供給に応じて誘起電流を生じさせる第２コイル部と、前記電流の前記供給によって生じた磁束の方向を、前記第１コイル部と前記第２コイル部との間で、変化させ、漏れインダクタンスを調整するための調整部と、を備えるコイル構造体を開示する。前記ボビン構造体は、前記調整部を保持する。【選択図】図２
