A Comparative Study of Four Different Non-Isolated Bidirectional DC-DC Converters

Abstract

Inthis paper, four different topologies of Non-Isolated Bidirectional DC-DC converters are compared. Their modes of operations and the design of passive components are presented in detail for all the topologies. The selected topologies are simulated by using MATLAB /Simulink to verify the effectiveness of the converters. The simulation results and comparative studies are used to select the efficient topology. Finally, a 12-V/50-V Prototype model is implemented to verify the feasibility of the converter for the application of Uninterruptible Power Supply
