| Abstract |
The well adopted approach to analysing DC and low-frequency behaviour of PWM DC-DC converters is through the notion of state-space averaged-circuit models. In this paper a related approach is exploited. It starts directly from the circuit graph and topological matrix description but in contrary to previous contributions it is proposed here to split the models in two distinct categories: the incremental model (introduced in this paper) and the averaged model (adopted in the literature) depending on whether the topological degeneracies are present or not in the converter graphs, respectively. A unified-form combined-graph model is proposed resulting in the reduced number of system equations and simplest possible means for evaluating DC and AC network functions.
Illustrative DC modelling examples concerning nondegenerate, semidegenerate and degenerate converters are included. |
