A comprehensive review on Bidirectional traction converter for Electric vehicles

In this fast-changing environmental condition, the effect of fossil fuel in vehicle is a significant concern. Many sustainable sources are being studied to replace the exhausting fossil fuel in most of the countries. This paper surveys the types of electric vehicle’s energy sources and current scenario of the on-road electric vehicle and its technical challenges. It summarizes the number of state-of-the-art research progresses in bidirectional dc-dc converters and its control strategies reported in last two decades. The performance of the various topologies of bidirectional dc-dc converters is also tabulated along with their references. Hence, this work will present a clear view on the development of state-of-the-art topologies in bidirectional dc-dc converters. This review paper will be a guide for the researchers for selecting suitable bidirectional traction dc-dc converters for electric vehicle and it gives the clear picture of this research field

Stability Analysis of a Novel Switched Inductor Based Quadratic Boost DC-DC Converter

This paper proposes a new Switched Inductor based Quadratic Boost (SLQB) converter. The theoretical study for control design is carried out in detail. Small signal dynamic analysis of the proposed topology is obtained by State-Space averaging technique to investigate the closed-loop performance of SLQB converter. Ziegler-Nichols' closed loop tuning method is adapted to design the controller and analyze the closed loop performance. The theoretically derived transfer functions divulged a perfect matching with simulation results obtained from circuit simulator, spice. The effectiveness and adaptability of the SLQB converter are confirmed with high gain DC-DC converters belonging to the SL family. The stability study is carried out by MATLAB software, and the respective graphs are obtained to analyze the open loop and closed loop performance of the derived converter.
