Design of Series Inductances in Triple Active Bridge Converter Using Normalization Procedure for Integrated EV and PV System

Triple active bridge (TAB) converter is one of the most useful converter circuits for electric vehicle (EV) and photovoltaic (PV) combined system. This paper proposes a design method for series inductances in TAB converter based on the normalization procedure. The design method is verified to design TAB converter for integrated EV and PV applications as 400 V − 10 kW. A prototype of TAB converter rated 100 V − 125 W is implemented to verify the proposed method. The experimental results show that the converter can work with the maximum power requirement for the full voltage range as the designed target. It shows that the proposed method can be applied to design the TAB converter.
