Electroactive Graphene–Polymer Nanocomposites for Self-Sustaining and Multifunctional Flexible Devices
Abstract: Graphene–reinforced polymer–composites were developed and systematically investigated to explore their multifunctionality in flexible electronic applications. The study specifically aims to correlate graphene-induced structure–property–function relationships with electroactive performance and self-sustaining behaviour in flexible devices. The hybridization of electroactive polymers—polyaniline (PANI), poly(3,4-ethylenedioxythiophene): polystyrene sulphonate (PEDOT:PSS), and polyvinylidene fluoride (PVDF)—with graphene nanoplatelets enabled simultaneous enhancement of electroactivity, energy-harvesting, and sensing functionalities. Morphological studies confirmed uniform graphene dispersion at 5 wt.% loading, forming continuous …

Power System Stability Enhancement Using UPFC
Abstract: AbstractThe UPFC consist of two voltage-source converters, one connected to the power system through a shunt transformer, whereas the other is inserted into the transmission line through a series transformer. These two voltage-source converters are coupled through a common dc capacitor link. From the control perspective, the UPFC can be decoupled into two branches; the parallel branch formed by the shunt transformer, voltage source converter and dc capacitor operating as …

A Contribution to the Frequency and Transient Analysis of High Voltage Bushings
Abstract: The paper suggests a method for determining the frequency characteristics and transient response of capacitively graded high voltage bushings. It is based on an s-domain circuit model that describes the grading conducting foils and the insulating layers. In most cases, they are of different axial lengths. A system of simultaneous differential and algebraic equations is derived taking these differences into account. Its closed-form solution, subject to the boundary conditions, can …

Study of Cascaded H Bridge Multilevel Inverter
Abstract: The inverters are now-a-days used broadly. Inverters are classified as two level inverters and multilevel inverters. There are too many limitations; conventional inverters at high power and high voltage applications. So, multilevel inverters become useful for high power and high voltage applications due to their increased number of levels at the output voltage. The harmonics are reduced by increasing the number of levels and output voltage has a tendency to-end-up …
