Modelling and control of a bidirectional single-phase single-stage converter for plug-in electric vehicles

In this paper, the modelling and control of a bidirectional single-phase single-stage converter for plug-in electric vehicles (PEVs) is presented. A nonlinear sliding mode controller with boundary layer solution and a redefined sliding manifold is proposed to enforce a pseudo-resistive relation between the input voltage and current. Based on the pseudo-resistive relationship obtained between the input voltage and current, sliding mode control approach is utilised to regulate the input resistance of the converter to a desired value, hence allowing charging and discharging of PEVs. Numerical simulation results are presented that evaluate performance of the proposed modelling and feedback control scheme.
