Small Signal Model of the Buck-Boost Bidirectional DC-AC Converter Based on Unfolding Circuit
This document presents an approach for getting and calculation the parameters of Proportional- Resonant (PR) controller for the twisted-bidirectional buck-boost inverter based on unfolding circuit. The obtained results are suitable theoretical guidelines for an investigation of selected topology dynamic. The results of small signal model allow estimating the stability of the system. The simulation results of grid-connected inverter based on the PR controller are presented. As the result simple PR controller without any compensation block is stable, but can't provide high accuracy of the grid current in real experiment.
