A Single-Objective Modulated Model Predictive Control for a Multilevel Flying Capacitor Converter in a DC Microgrid

This paper presents a single-objective modulated model predictive control for bi-directional DC-DC flying capacitor (FC) converter in microgrid. The presence of FC facilitates the to integrate low-voltage battery high-voltage DC bus at reduced voltage stress on its power switches. such configuration demands multi-objective controller accomplish and regulations, flow. proposed realizes these multiple objectives by determining optimum duty ratio switches using cost function based current. In doing so, without weighting factors operates fixed switching frequency. also eliminates an additional loop utilizing improved dynamic reference generate appropriate current regulation Finally, system is validated experimentally under step-response voltage, load, PV power, parameter variations, compared with finite set prove effectiveness.
