Abstract: The line-to-output (LTO) frequency response of switched DC-DC converter describes how the small-signal harmonic perturbation of the converted input DC voltage penetrates into the converter output, depending on the frequency of this perturbation. In the paper, the LTO frequency response conceived in this sense is faced with the LTO response, obtained by applying the well-known State-Space-Averaging (SSA) technique to switched converters, with the aim of determining the fundamental limitations of the SSA-approach. The general analysis is then applied to Buck-, Boost-, Buck-Boost-, and Cuk- type converters. It is shown that the accuracy of SSA outputs is related to the character of the state matrices of the converters.
