Distributed control of phase leg cell in the full-bridge voltage source inverter

The distributed control within a power converter is studied in this paper. In the converter the integrated power electronics module of phase leg cell is used as the distributed part. Many topologies can be constructed flexibly in which the separated controllers replace the conventional concentrated controller. We focus on the distributed control strategies for single-phase full-bridge voltage source inverter in this paper. The characteristics of the new structures are discussed and the effects of the parameter dispersivity in the inverter are analyzed. The simulation and experimental results of each case are included.
