The paper presents the control design of on-board two-stage electric vehicle (EV) charger. The first stage AC-DC converter of EV charger plays a very important role in supporting the grid reactively. Therefore, a reduced order plant integrated proportional integrating (PIPI) controller has been designed for first stage of EV charger. Generally, a proportional resonant (PR) regulator is used for tracking of grid current reference in control of AC-DC converter. However, conventional PR regulator is a third order system due to that the complexity of controller is increased. To reduce the complexity of controller, a first order PIPI regulator has been designed which has all the functionalities of conventional PR regulator and can track any periodic signal. This method is implemented in inner current control loop of first stage AC-DC converter. This results the reduction in controller complexity and better dynamic response as compared with conventional PR regulator.
