Query: A Building-Block Approach to State-Space Modeling of DC-DC Converter
  Systems   Small-signal models of DC-DC converters are often based on a state-space
averaging approach, from which both control-oriented and other frequency-domain
characteristics, such as input or output impedance, can be derived. Updating
these models when extending the converter by filters or non-trivial loads, or
adding control loops, can become a tedious task, however. To simplify this
potentially error-prone process, a modular modeling approach is being proposed
in this article. It consists of small state-space models for certain building
blocks of a converter system on the one hand, and standardized operations for
connecting these subsystem models to an overall converter system model on the
other hand. The resulting state-space system model builds upon a two-port
converter description and allows the extraction of control-oriented and
impedance characteristics at any modeling stage, be it open loop or closed
loop, single converter or series connections of converters. The ease of
creating more complex models enabled by the proposed approach is also
demonstrated with examples comprising multiple control loops or cascaded
converters.
