WITHDRAWN: Investigation of Non-isolated Dual Inputstep-up Dc-dc Converter Using Sliding Mode Control for Ev Application

Abstract

This work investigates the design and implementation of a slide mode controller for a high step up dual input non-isolated dc-dc converter for Electric vehicle applications. The proposed high step up dual-input dc-dc non isolated converter comprises one inductor, one capacitor, two switches with anti parallel diodes, and two switches without diodes. The converter analysis is carried out using state space averaged model. The converter with the slide mode controller is analyzed by varying both the input voltage and the load. The performance characteristics of the proposed converter is compared against the conventional PID controller, and it is found that the high input step-up dual input dc-dc non-isolated converter with slide mode controller shows improved performance. The proposed converter is dynamic and exhibits a high-speed step-up conversion ratio. The slide mode controller is designed, analysed and it is simulated. The simulation results are validated by developing a prototype model. The proposed converter is simple in construction, highly reliable, and efficient. Further, the converter exhibits less input current ripple and low electromagnetic interference which makes it the best choice for Electric Vehicle applications.
