The T-type DAB converter outputs two waveforms: a square wave and a square waveform with half of the input voltage. By applying the switching operation mode, the converter efficiency is improved. In addition, voltage control for the T-type DAB converter is also proposed. Owing to the proposed voltage control, the slow voltage response is avoided because the operation modes are seamlessly switched by matching the transferred power of each mode. In an experiment conducted using a 1.5-kW prototype, the validity of proposed method is confirmed. A maximum efficiency of 97.9% is achieved at the nominal voltage condition. At the half-output-voltage condition, the converter loss is reduced by up to 62.3%, when the switching mode is applied. Moreover, the output voltage control is effective, regardless of switching operation mode.本誌: 電気学会論文誌D（産業応用部門誌） Vol.139 No.4 （2019） 特集：平成30年産業応用部門大会本誌掲載ページ: 388-400 p原稿種別: 論文／日本語電子版へのリンク: https://www.jstage.jst.go.jp/article/ieejias/139/4/139_388/_article/-char/ja/
