Purpose. This article proposes a new control strategy for Dynamic Voltage Restorer (DVR) in utility grid for distribution system. The proposed DVR using PI tuned fuzzy logic scheme is based on replacement of conventional DVR and voltage sag compensation in distribution system network. The novelty of the proposed work consists in presenting an enhanced PI tuned fuzzy logic algorithm to control efficiently the dynamic voltage restorer when voltage sag is suddenly occurred. Methods. The proposed algorithm which provides sophisticated and cost-effective solution for power quality problems. Our strategy is based on tuned fuzzy control of reactive powers and also closed loop for harmonic reduction in distribution system. The proposed control technique strategy is validated using MATLAB / Simulink software to analysis the working performances. Results. The results obtained clearly show that DVR using PI tuned fuzzy logic have good performances (sag compensation, harmonic reduction) compared to conventional DVR. Originality. Compensation of voltage sag/ swell in distribution for reactive power and current harmonic reduction by using DVR based PI tuned fuzzy logic controller. Practical value. The work concerns the comparative study and the application of DVR based on PI tuned fuzzy techniques to achieve a good performance control system of the distribution system.

This paper proposes the design of a controller using the artificial neural network (ANN) for a solar photovoltaic (PV)-fed cascaded multilevel inverter (CMLI) to enhance the power quality. The objective of this presented ANN controller is to obtain a maximum output voltage with no filter components. This paper also investigates and eliminates the voltage harmonics that occurred in a solar-fed cascaded 3-stage inverter using various techniques such as pulse width modulation (PWM), digital logic control (DLC), fuzzy logic controller (FLC), and ANN, and the results are compared. Based on the results, the proposed ANN-based controller efficiently reduces harmonics and improves the power quality. This is achieved by solving the harmonic equations and thereby changing the switching angles of each semiconductor to a minimum value. The ANN is trained by a dataset consisting of varying input voltage and switching angles. The simulation was performed using MATLAB/Simulink for different types of controllers like PWM, DLC, FLC, and ANN for the 3-stage inverter. The simulated results are compared with the results obtained from a 3 kWp photovoltaic plant connected to the CMLI. Finally, on the basis of performance analysis, it was confirmed that the ANN-based controller effectively eliminates harmonics and improves the power quality.

“…There are two independent inner current loops controlled by two PI controllers for d‐axis and q‐axis currents, respectively, and an outer speed control loop taken care of by another PI controller. Initially, the inner PI controllers are tuned using the Ziegler Nichols tuning method as described in References 17 and 34 till the desired values of i q * (arbitrarily chosen) and i d * (zero) are obtained without saturating the inner PI controllers. Thereafter, the outer PI controller is finally tuned to attain a desired reference speed.…”

Summary Electric vehicles (EVs) require an extremely efficient power train unit consisting of converters with very low power losses and a motor with excellent controllability, long life, and an extended speed range. Consequently, permanent magnet synchronous motor (PMSM) drives are increasingly becoming popular for EV applications due to their higher torque density, better efficiency, and rugged structure. This paper explores the reduced switch five‐level transistor—clamped H bridge (TCHB) inverter topology for driving a PMSM, particularly for an EV application. The TCHB inverter emulates the modular structure of a cascaded H bridge (CHB) inverter, with each phase being energized by independent DC sources, thereby making it a natural fit for EVs. Simplified loss models have been developed to estimate the conduction and switching losses in the TCHB and CHB inverter circuits to assess their suitability for EV applications. An experimental prototype of the TCHB inverter, triggered with a novel space vector‐based modulation scheme, feeding a vector‐controlled PMSM has been designed, developed, and tested to ascertain the efficacy of this inverter‐motor electrical drive system for light‐duty EV applications, with regard to reduced losses, better DC bus utilization, diminished torque ripples, and improved dynamic response.
