Three-level Bidirectional DC-DC Converter

JIN Ke, YANG Meng-xiong, RUAN Xin-bo (Nanjing University of Aeronautics & Astronautics, Nanjing 210016, Jiangsu Province, China)  
A novel three-level bidirectional converter is proposed in this paper. Compared with the traditional bidirectional converter, the voltage stress on the switch of the proposed converter is just half of high voltage port. Low voltage port and high voltage port share the ground, which leads to easy to control. The inductor of three-level bidirectional converter also can be reduced significantly, so the dynamic response can be improved. Therefore, it is very suitable for distributed power systems, like fuel cell, photovoltaic and wind power systems, etc. This paper also illustrates the operation principle and implementation of the control circuit. Interleaved and complementary drive control, bidirectional control, and voltage control of the flying capacitor for the new converters are presented in details. A 1kW prototype converter is built to verify the theoretical analysis and the effectiveness of the control strategy.
