Distributed Interleaving of Paralleled Power Converters
This paper introduces a distributed approach to interleaving paralleled power converter cells. Unlike conventional methods, the distributed approach requires no centralized control, automatically accommodates varying numbers of converter cells, and is highly tolerant of subsystem failures. A general methodology for achieving distributed interleaving is proposed, along with a specific implementa...
متن کاملRobust Control Design for Paralleled Dc/dc Converters with Current Sharing
This paper concerns a robust control design for multi-loop operation of paralleled DC/DC converters in the presence of uncertainties. The system is composed of voltage-loop and current-loop subsystems. The PID controller is firstly designed to achieve the robust stability and robust performance of the voltage-loop. Then, the PI controller for the current-loop is designed to achieve the robust s...
متن کاملA Repetitive Control- based Approach for Power Sharing among Boost Converters in DC Microgrids
In this paper a repetitive control (RC) approach to improve current sharing between parallel-connected boost converters in DC microgrids is presented. The impact of changes in line impedance on current sharing is investigated. A repetitive controller is designed and connected in series with current controller of the boost converters to control the switching signals such that by regulating of th...
متن کاملA Feedforward 10× CMOS Current-Ripple Suppressor for Switching Power Supplies
With the advent of wireless microsensors and other microscale applications, switching supplies fully integrated on chip or into the package are desirable and often necessary. The problem with small inductors is that they exhibit low inductance and larger equivalent series resistance (ESR); in other words, they induce larger ripples in the output and higher conduction power losses. This brief pr...
