Feed-Forward based Control in a DC-DC Converter of Asymmetric Multistage Stacked Boost Architecture

Alfred Rufer, Gina Kristin Steinke, Georgios Mademlis

A new feed-forward control technique for a DC-DC step-up converter based on the asymmetric Multistage Stacked Boost Architecture (MSBA) is proposed. The devel-oped feed-forward controller directly handles the load current and the perturbations that may be ...
