Analysis and simulation of a three-phase push-pull/flyback interleaved bidirectional dc-dc converter

This paper presents a new bidirectional dc/dc converter topology, which is composed of three-phase push-pull and interleaved flyback converter. The two directions operation of the proposed converters is analyzed and explained even as the DC transfer function of the circuit versus the duty ratio has been presented. The main advantages of this topology are high switching frequency, lower input current ripple, smaller output capacitor, less number of switches and the frequency of output voltage and input current ripple are three times the switching frequency. A simulation model is developed in the OrCAD Capture simulator. Then, the simulation results will verify the validity of the mathematical and theoretical analysis.
