A New Buck/Boost Bidirectional DC/DC Converter Base on Soft Change Current Network

Abstract:

There is a problem about high current and voltage spikes in Buck and Boost converters,it will damage main power devices .Therefore, a novel Buck/Boost bidirectional DC/DC converter based on soft change current (SCC) network was given, and Buck and Boost modes ware particularly analyzed.Groups parameters of L/C/D are selected and simulated with Saber software. The optimal combination of L/C/D was ascertainned by observing groups switch waveforms. Theoretical analysis and simulation results show that the voltage and current spike of the power switches is deeply descreased by SCC network.
