Dynamic behaviour of a ring coupled boost converter system with passivity-based control
For researchers in power electronics and distributed generation, this work presents a control method for ring-coupled converter systems, but the results are numerical only and the approach is incremental.
This paper applies passivity-based control to a ring-coupled boost converter system for dispersed DC generation, achieving robust stabilization at a desired DC voltage under external disturbances as demonstrated by numerical results.
This paper discusses a dispersed generation system of multiple DC/DC converters with DC power sources connected in a ring formulation. Here is presented the analysis of the system based on the stored energy and passivity characteristics of the system. Passivity Based Control (PBC), with its energy-modifying and damping-injection technique, is applied to a ring coupled converter system to stabilize itself at a desired DC voltage in the presence of external disturbances. The numerical results reveal the effective application of the control as a robust and flexible technique.
