This work proposes a cost effective with a compact power electronic interface for plug-in electric vehicles (PEVs), which has the ability to achieve the all modes of vehicle operation, including plug-in charging, propulsion (PR) and regenerative braking (RB) for on-board applications. The proposed converter for PEVs has minimum component count as well as step-up and step-down operation ability depending upon the system requirement. The capability of the proposed converter to work in both the modes allows wide range of battery parameters selection, efficient DC-link voltage regulation and offers more flexibility in RB. Moreover, a current sensing based (without voltage sensor) non-linear carrier control (NLCC) technique for power factor correction has also developed in this work. This control scheme improves the reliability and stability of system by reducing the feedback circuitry. A prototype of the proposed charging system is established and analysed to an authenticate the effectiveness of developed system under steady state and dynamic conditions.
