Efficient Voltage Regulation for Stand Alone Photovoltaic Cell using PI Controller for AC Voltage Application
Abstract— This paper focuses on the renewable energy system PV (Photo Voltaic) Cell in stand alone model. The system consisting of solar PV cell, DC-DC Boost converter, and inverter coupled to the load system. An 18V photovoltaic cell and a DC-DC boost converter is designed for the purpose of boosting the PV cell output voltage. The advantage of using the proposed DC-DC converters are only one sensor is required, high ....etc

A NEW METHOD FOR POWER QUALITY IMPROVEMENT IN CLASSICAL AC/AC VOLTAGE CONTROLLER USING PWM TECHNIQUE
INTRODUCTION
AC voltage controllers, allow controlling the output voltage only, while the output frequency is the same as the input frequency.
AC voltage controllers are widely used to obtain variable AC voltage from fixed AC source. Triacs or thyristors are usually employed as the power control elements of such controllers.
Advantages include simplicity and ability of cont ....etc

A High Input Voltage Three-Phase ZVZCS DC-DC Converter with Vin /3 Voltage Stress on Primary Switches
Abstract
A high-voltage three-phase ZVZCS dc-dc converterwith low voltage stress is presented in this paper. The voltagestress on the primary switches is only one-third of the inputvoltage. By using the phase shift pulsewidth modulation (PWM)and secondary snubber, four of the six primary switches areoperating with zero-voltage switching (ZVS) and two of them areoperating with zero-current switching (ZCS), in order to reducethe switch ....etc

A Neural-Network-Based Space-Vector
PWM Controller for Voltage-Fed
Inverter Induction Motor Drive




abstract

neural-network-based implementation of
space-vector modulation (SVM) of a voltage-fed inverter has been
proposed in this paper that fully covers the undermodulation and
overmodulation regions linearly extending operation smoothly
up to square wave. A neural network has the advantage of very
fast implementation of an SVM algorithm that can increase the
converter switching frequency, pa ....etc

Voltage source inverters (VSI) have been widely used in uninterruptible power supplies, unified power flow controllers or unified power quality conditioners, and distributed generation systems (DGS). VSIs are inherently efficient, compact, and economical devices used to control power flow and provide quality supply. VSIs can be classified as voltage-controlled VSIs (VCVSIs) and current-controlled VSIs (CCVSIs), depending on their control mechanism. In this paper, a detailed comparison of VCVSIs and CCVSIs for DG ....etc
