Investigations on FOPID/SMC Based Modified Four-Port Converter for EV Applications

This work shows the analysis of modified structure of non-isolated multiport converter used for electric vehicle (EV) applications with reduced switch count. A streamlined control scheme is used which increases the converter's dependability and economy. This structure can interface any energy source with different performance characteristics. It has a capacity to increased or decreased output voltage It has bidirectional power flow capacity. The converter has been analysed under different operating conditions. A novel control scheme termed as Sliding-Mode-controller (SMC) has also been proposed to control the transfer of power between ports. The steady state performance of the converter and its functionality has been confirmed by MATLAB simulation and by prototype setup.
