This paper investigates the effect of reconfiguration and network type (mesh/radial) on small signal stability margin of a droop-based islanded microgrid. A low voltage microgrid and standard IEEE 33 bus system (with three and five sources) are considered for study. From eigenvalue analysis and root locus plot, it is found that the reconfiguration and network type has significant effect on small signal...
This paper presents a systematic derivation of small signal model of current-fed isolated full-bridge dc/dc converter with an active clamp. Active-clamp is an active snubber helps to absorb turn off voltage spike across the power semiconductor devices, thus limiting or clamping the voltage across the devices. Inherently, it results in zero-voltage-switching (ZVS) of all devices (main and auxiliary)...
