Abstract

This paper describes a power electronic system that, among other possibilities, can be used to charge electric vehicle batteries. A large-signal linear multirate digital controller for the charging current permits the charger to track and deliver a desired current trajectory for a wide range of loads. This controller simultaneously ensures that the charger draws power from the electric utility with unity power factor. The analytical development of the controller and experimental results from a prototype charger are presented
