Enhanced Average-Value Modelling of Interleaved DC-DC Converters Using Sampler Decomposition

Research output: Contribution to journalArticle

Abstract

To provide a basis for controller design in interleaved dc-dc converters, an improved small-signal averaged model is presented. Sampler decomposition techniques are used to represent the interleaved operation of the individual control loops within the converter. The resultant model reveals interaction effects and instability phenomena that are not predicted by a simple non-interleaved model, and which impose significant restrictions on the selection of control parameters. The model is validated by detailed simulations and experimental results from a digitally controlled, dual-interleaved boost converter.
