An average model of dc–dc step‐up converter considering switching losses and parasitic elements

Power electronic converters represent a cornerstone of modern power systems, especially since the introduction of generation from renewable energy sources, such as photovoltaics. One of their main features is their high flexibility in converting different voltage levels and waveforms.

As with all conversion devices, they are subject to inevitable losses introduced by non-ideal components. For this reason, in recent decades, numerous research activities have been dedicated to modeling their behavior and predicting overall efficiency. Despite the number of scientific publications on the topic, non-idealities have rarely been studied in terms of their impact on the input-output characteristics of the converter. In this document, the conventional equivalent circuit of a DC/DC step-up converter has been updated to introduce the effects of both conduction and switching losses. The resulting formulation, extendable to all DC/DC converters, allows for a more accurate average model and is particularly suited for studying multi-converter architectures, such as those used in the latest renewable energy applications. Finally, thanks to a dedicated test setup, the results of an experimental campaign demonstrate how the new formulation accurately predicts its electrical behavior.
