Development and application of numerical models for the evaluation of power systems

The modeling and control of dc to dc voltage converters is discussed. The use of the current injection method yields low frequency small signal models that are sufficiently precise to evaluate different parasite phenomena. The output authorizes the use of a command to return the variables of the physical state and of the modal control. A generally accurate model of the limit-cycling conductance controller is used to obtain models of a boost cell. The introduction of input and output filters is considered as well as stoppage time. The general problem of compensation is discussed.
