Present work aims to improve the dynamic response and reliability of Shunt Hybrid Active Filter (SHAF) configuration using improved methods of harmonic detection. A method of introduction of only “positive inductance” through an active filter for mistuned conditions of the passive filter has been presented. “PLL free” scheme of harmonic detection for an uncontrolled rectifier type of non linear load...
A technique has been presented for reducing the injection of harmonic current into the grid for matrix converter controlled induction generator, for application in wind energy conversion systems. A composite arrangement has been proposed where, multiple matrix converter controlled induction generators are kept in parallel and connected to the grid with appropriate phase shifting transformers that...
In this paper electric power generation from wind is achieved by directly coupling wind turbine to a squirrel cage induction generator without gear box. A matrix converter (MC) is used as an interface between the grid and the generator for direct to grid power injection. For the control of the induction generator voltage and frequency, a cosinusoidal modulation technique for switching of matrix converter...
The paper describes a technique for current harmonic reduction at the grid side of matrix converter controlled induction generator systems for application in gearless wind energy conversion system. A composite arrangement has been proposed where, multiple co-sinusoidal modulated matrix converter that are controlling induction generators are kept in parallel and connected to the grid with phase shifting...
