Nonlinear MIMO Control of Interleaved Three-Port Boost Converter by Means of State-Feedback Linearization

Abstract

Application of feedback linearization control to interleaved three-port boost converter is presented. The control presents a fast transient response and is able to share the current between the two branches of the converter while controlling the output voltage for standalone operation. In order to extend its operation range and make it able to work in different operating points, an outer loop for the current reference generation is used. Simulation results are presented showing the proposed operation of the converter and its features are discussed.
