This paper is with regard to a topology of an interleaved bidirectional buck-boost power converter for railway applications. The objectives of this proposed power converter topology are to suppress the harmonics at the both sides of the input terminal and output terminal using this topology. Since the both sides of voltages have wide operating ranges such as the battery voltage ranging 500V∼700V, and the DC link voltage ranging 500V∼1000V, the control algorithm for this power converter is investigated especially at the aspect of smoothing transients caused by the changes of current direction and the modes of operation(buck or boost modes). Control design, and simulation and experiment results are presented to validate the proposed system.
