Simulation Research of a Soft Power Bi-Directional DC-DC Converter

Abstract:

A type of BUCK/BOOST bi-directional DC-DC topology for high power occasions was presented based on the main circuit topology shortcomings of conventional BUCK/BOOST bidirectional DC-DC converter by increasing the inductance, capacitance, diode auxiliary circuits, the work process of the main circuit BUCK BOOST in the simulation state was analyzed. Select multiple sets of parameters on simulation, observe the waveform ON and OFF of main power device to determine the appropriate auxiliary circuit parameter set. The results show that: The topology suppresses large current peak of the main power device and improve the reliability.
