The present paper deals with RST controller using implementation of neural architectures to control power electronics systems dedicated to power quality improvement in a distribution grid. We present a technique for designing a robust RST controller, The computation of the controller is used to enhance the control a Hybrid Indirect Matrix Converter with a flying capacitor three level inverter (HIMC) coupled to the power grid (PG) by an RL filter, the synthesizing of this RST controller is formulated through open and close loop. Artificial neuronal network (ANN) identification technique is used to define/extract this disturbance. Simulation results by MATLAB, Simscap/sim power system code shows the effectiveness of the proposed method.

In this paper, a PWM inverter is proposed for improvement of power quality i.e., reduction of total harmonic distortion (THD). The power quality problems reduce the lifetime and performance of equipments. The proposed system reduces the THD which is generated from the nonlinear loads. Because presence of harmonics leads to problems like overheating, failure of insulation etc. Here the simulation results of the proposed system is studied using MATLAB SIMULINK. Using the system, a lower THD is achieved which shows the effectiveness of the system.

This paper proposes a hybrid filter to minimize the power quality impact of matrix converters. Matrix converters inject significant harmonics and nonstandard frequency components into power systems. The hybrid filter is used to reduce the harmonics. A hybrid filter constructed of a shunt active filter and distributed passive filters used for power quality improvement. The proposed approach has been tested and validated on the matrix converter using Matlab/Simulink. The comparison of Simulation results for passive and active filter separately used with matrix converter with the result of matrix converter with hybrid filter is shown to demonstrate the advantages of the proposed scheme.
