Lyapunov-based control of single-phase AC-DC power converter for BEV charger

In this paper, we consider the problem of controlling single-phase ac-dc power converter for BEV (battery electric vehicle) charger. The control objectives are threefold: i) ensuring a unitary power factor (UPF) in grid-side, ii) regulating the dc-bus voltage to its constant reference in dc-side, and iii) ensuring asymptotic stability of the closed loop system. Based on the nonlinear model of the studied system a nonlinear controller is designed using Lyapunov approach. In order to validate the effectiveness of the proposed nonlinear controller, several numerical simulations are performed using the Matlab/Simulink software.
