Abstract

The paper deals with small-signal analysis of DC-DC power converters with sliding mode control. A suitable small-signal model is developed, which allows selection of control coefficients, analysis of parameter variation effects and characterization of the closed-loop behavior in terms of audiosusceptibility, output and input impedances and reference-to-output transfer function. Unlike previous analyses, the model includes effects of the filters used to evaluate state variable errors. Simulated and experimental results demonstrate model potentialities
