This paper analyzes the influence of state feedback coupling between the capacitor voltage and inductor current in voltage source inverters (VSI) operating in stand-alone microgrids. A decoupling technique is proposed as an effective measure to enhance the dynamics. Further implementation issues and control structures are also considered. Lab-scale experimental results prove the validity of the approaches.
Inner current and voltage loops are fundamental in achieving good performance of microgrids based on power electronics voltage source inverters. The analysis and design of these loops are essential for the adequate operation of these systems. This paper investigates the effect of state feedback coupling in the design of proportional resonant controllers for these inner loops in voltage source inverters...
This paper presents a monolithic CMOS low drop-out regulator for adaptive wireless powered bio-implants. A dual-loop control scheme is proposed to enhance load/DVS transient response, without a filter capacitor. The inner loop employs a direct dynamic coupling technique to improve transient response by directly detecting voltage variations through a capacitive coupling high-pass filter. Meanwhile,...
