Title
(EN) INSULATED BIDIRECTIONAL DC/DC CONVERTER AND CONTROL METHOD THEREFOR
(JA) 絶縁型の双方向DC/DCコンバータおよびその制御方法
Abstract
(EN)

PROBLEM TO BE SOLVED: To provide an insulated bidirectional DC/DC converter which suppresses a DC current component.

SOLUTION: In a DAB converter, an intermittent operation in which a transmission period and a non-transmission period are alternately generated is implemented. During the non-transmission period, an inductance current iac1 is made flow, thereby performing zero voltage switching ZVS.

【課題】直流電流成分を抑制した絶縁型の双方向DC/DCコンバータを提供する。
【解決手段】DABコンバータにおいて、伝送期間と非伝送期間を交互に発生させる間欠運転を実施する。非伝送期間の間、インダクタンス電流iac1を流すことにより、ゼロ電圧スイッチングZVSを行う。
