A MODELLING METHOD FOR THE BEHAVIOUR OF CONVERTERS OPERATING IN CONTROL LOOPS

The models available to study the dynamic behaviour of control loops including power convertors can be separated in two classes : those very simplified or those very sophisticated. In this paper, we give a method which takes place between the two classes and we obtain non linear continuous models for large signal or linear continuous models for small signal. Some examples show the good agreement between the corresponding results and those obtained by using more accurate methods.
