Due to large amount of non-linear power electronic equipment’s impact and fluctuating loads , problems of power quality have become more and more serious with each passing day. Active power filtering has gained much more importance in the power quality arena as it gives the best solution for all power quality issues. Shunt active filtering is effective and the performance of such units largely ...

This paper presents a novel stationary frame selective harmonic extraction strategy. Compared with the widely used methods based on the instantaneous power theory, it only needs one matrix transformation, which significantly reduces the computational burden. Time-domain simulation in the MATLAB/Simulink and experimental results based on the 32-bit fixed-point TMS320F2812 DSP platforms verify th...

In this paper a control algorithm is validated with simulation studies in MAT environment and experimental studies are performed in to validate the proposed control algorithm. The projected algorithm to compensate the nonlinear and loads in three phase four wire distribution system using shunt active power filter. In this algorithm a positive sequence extraction of the supply voltage and the th...

This paper presents a novel way of generating the reference currents for an active filter and/or a static compensator. A compensator structure is proposed which is capable of balancing an unbalanced delta-connected load that may also draw harmonic currents. In addition to balancing the load, the supply side power factor is also made unity. The theory of instantaneous symmetrical components is u...

We study the modified theory of gravity in Friedmann Robertson Walker universe composed of several perfect fluids. We consider the power law inflation and determine the equation of state parameters in terms of the parameters of modified gravity’s Lagrangian. We also discuss briefly the gravitational baryogenesis in this model.
