Zusammenfassung:This paper describes a large-signal linear, multirate digital controller for, among other possible servomechanical applications, charging electric vehicle batteries. This controller permits the power amplifier to track and deliver a desired current trajectory for a wide range of loads while providing a unity-power-factor interface to the electric utility. A computationally inexpensive technique for implementing output ripple cancellation is also described and demonstrated on a prototype converter.
