In order to reduce the volume and size of distribution power transformer, precise and extended controlling of transformer output, the conventional transformers are replaced by intelligent universal transformers (IUTs). In this paper, an IUT, typical of Iran national grid, with the voltage ratio of 20kV:380 V is designed and simulated. Regarding the IUT implementation, a cascaded H-bridge invert...

This review provides a survey of shunt active power filter based on inverter in three phase four wire system. These topologies are applied to solve problem due to non linear load in power system network such as a power quality issue, reactive power compensation and harmonic current suppression. In making a review it should be noted that this paper will not attempt to give an all encompassing re...

This paper proposes a photovoltaic (PV) and battery interfaced series hybrid active power filter (SHAPF), which consists of series active power filter and an LC shunt passive filter. The main benefits of the proposed system provide the compensation against the voltage harmonics, current harmonics and voltage interruption for the whole day. A series active power filter (SAPF) demands a source of...

This article (case study) discusses the influence of household photovoltaic generation on voltage quality in a three-phase 0.4 kV grid. The research analyzes remotely acquired data from two specially designed Y-connected power meters to understand PV system’s values voltages, currents, THD, individual harmonics, factor, and K-factor are obtained every 200 ms over several months, creating more t...

This article presents an experimental confirmation of a constant DC-capacitor voltage-control (CDCVC)-based strategy for active power-line conditioner (APLC) in three-phase four-wire distribution feeders (TPFWDFs). A calculation block the fundamental-active current feeder currents is added to previously proposed CDCVC-based APLC laboratory-scale model. The results demonstrate that DC component ...

This paper deals with a integrated Electronic Load Controller (IELC) for an isolated asynchronous generator (IAG), used in constant power pico hydro power generation for feeding three-phase four-wire loads. The proposed IELC is used to control the voltage and frequency of IAG in the integrated manner. This IELC is realised using a T-connected transformer and three-leg insulated gate bipolar tra...

A CMOS image sensor with an integrated wire grid polarizer to sense the polarization of light is presented. The chip consists of an array of 128 by 128 pixels, and it has been designed and fabricated in a CMOS 180nm process. The sensed polarization information is represented and analyzed in both the analog and the digital domain. Extinction ratios of 6.3 and 7.7 were achieved in analog represen...
