Abstract

The interests on energy storage schemes, bidirectional dc-dc converter and uninterruptible power supplies have been increasing nowadays as there wide researches are undertaken in the area of electric vehicles. A modified bi directional class-E resonant dc-dc converter is introduced here in this proposed topology for the application in electric vehicles. The advantages of soft switching techniques have been utilized for making analysis simple. The main advantage here in this system is that it can operate in a wide range of frequencies with minimal switching loss in transistors. This paper elaborates a detailed analysis on converter design and the same has been simulated and verified in Matlab/Simulink.

Highlights

During the last few decades, the impact on environment by the petroleum based transportation has driven towards electric motor based transportation
The electric vehicle [1]-[3] differs from the petroleum based vehicles in the sense that the electrical energy consumed by the electrical motor [4] can be generated by means of various and wide range of sources like nuclear energy, renewable energies and from fossil fuels
The dual active bridge converter [7] was used for this application, but this converter cannot achieve zero voltage switching [8] in varies range of load variations when input and output voltage rises

Summary

Introduction

During the last few decades, the impact on environment by the petroleum based transportation has driven towards electric motor based transportation. (2016) A Resonant Dual Full-Bridge Class-E Bidirectional DC-DC Converter for Fuel Cell Electric Vehicle. The dual active bridge converter [7] was used for this application, but this converter cannot achieve zero voltage switching [8] in varies range of load variations when input and output voltage rises. To eliminate this problem in control system the phase shift [9] [10] was introduced with the pulse width modulation. The drawbacks in the above said conventional types are eradicated in the proposed resonant based bidirectional dc-dc converter
