Abstract

This work investigates the design and implementation of a sliding mode controller for a non-isolated dual-input step-up DC–DC converter for electric vehicle applications. The non-isolated dual-input step-up DC–DC 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 sliding mode controller is analysed by varying both the input voltage and the load. The performance characteristics of the dual-input DC–DC converter are compared against the conventional PID controller, and it is found that the non-isolated dual-input step-up DC–DC converter with sliding mode controller shows improved performance. The converter thus considered is dynamic and exhibits a high-speed step-up conversion ratio. The sliding mode controller is designed, analysed and it is simulated. The simulation results are validated by developing a prototype model. The 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.
