What is it about?
The multi-stages operation of SITO converter and the parasitic elements cause obtaining a model to predict the all behaviors of converter be more difficult than typical converters. By SFG method, all small-signal transfer functions can be derived. Derivations of large-signal, small-signal and steady-state models are demonstrated by considering a single inductor triple output boost/boost convert.

Why is it important?
A Single Inductor Triple-Output converter (SITO) in continuous conduction mode (CCM) is modelled based on SFG method. An effort has been made to consider all mentioned unwanted parameters. Unified SFG model is developed for a SITO converter. The modelling errors is observed by comparing the experimental results with SFG model versus inductor ripple current.
Perspectives
The modelling errors are observed by comparing the experimental results with SFG model results versus inductor ripple current. The results show that the SFG model is good alternative for modelling switching converter with complicated structures in low inductor ripple current.
