Questions about BoostConve​rterExampl​eModel

Hello, I am learning to linearize DC-DC converter such as a Buck converter and plot its Bode Plot.When using the given example, BoostConverterExampleModel,I can only apply the AVG Voltage Model of the variant subsystem with the given script. When I try to use Detailed Model and Low Level Model with the given script, there some errors,"xoff(:,1,ct) = xFinal';". It seems to be about the number of States.How can I determine the number of States？So，what should I do if I want to use Detailed Model and Low Level Model subsyestem? Thanks.

Hi,

Only average model would linearize. The detailed model includes high-frequency switching that is introducing discontinuities into the model, and Linear Analysis Tool would return zero linearization. For linear analysis, work with the average model, for detailed time domain simulation, use detailed model.
