High Gain Modified Boost Converter for Electric Vehicle Battery Charging

Abstract

In this paper, a modified boost converter topology for electric vehicle charging from a photovoltaic source is proposed. The proposed topology offers higher voltage gain and lower ripple content over the conventional boost converter. Investigations into the characteristics of lithium battery load, selection of the photovoltaic panel rating are discussed. Simulation studies on the performance of conventional and modified boost converter are performed with a resistive load using MATLAB/ Simulink. Experimental results validate the simulation studies. The proposed topology has a single switch and results indicate higher voltage gain with a 22 V input stepped up to 51 V and higher output voltage with a 48 % moderate duty cycle. � 2019 IEEE.
