“…In general, complex load models will add state variables to the overall current-loop state-space description through the driving-point admittance In such cases, the currentloop state equations will generally be more complicated than those summarized in (12). Gains might have to be adapted and/or different compensation schemes might be needed for different loads.…”

“…This made it easy to step from (10) to (11), while developing the full-state equations (12) for the current loop in the previous section. For a more complicated LTI load model, the delay model of the voltage loop may not be as easy to apply.…”

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.

In a regulation application, a power supply is typically tasked with maintaining a fixed1 voltage or current in the face of possible disturbances. In a tnzcking application, on the other hand, a controller works to cause an average output voltage or current to follow a desired reference waveform as a function of time or some other variable. This paper describes a large-signal linear, multirate digital controller for, among other possible applications, charging electric vehicle batteries. This controller permits the charger 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.
