WITHDRAWN: DC-DC converter in electric vehicles using smart technology to reduce overall ripple current

Abstract

Abstract This study explores a possible EV design using supercapacitors and batteries to guarantee a reliable and rapid power transfer. The current flow is through a dc connected with an interleaved dc-dc transformer between the energy sources and the EV. This topology shows low number of components and great performance over a large range of loads, which is the right option for high strength, high current levels. The efficacy of the non-isolated converter is measured on the basis of this study. The efficiency of solar PV is low, so the converter is used to progressively lower the power level. A comprehensive design approach includes a qualitative and quantitative study of the converter, including a basic technique, i.e. the medium current mode control, and the implementation of the control system. The prototype of the lab converter with 2 kW uses the microcontroller dsPIC30f4011. Some specific waveforms are checked for the performance of the system. The principal advantages of the proposed solution are its high density, low component count and increased robustness. This is a viable option for practical EV applications.
