Abstract: A three-phase to single-phase matrix converter is investigated in the present paper. Based on the state matrix vector, a mathematical analysis of the converter is performed giving the relation between the sinusoidal line voltage (current) and the output voltage (current). The results of the investigation are confirmed using computer simulation of the converter by the program product C...

The development of a high-power-density three-phase ac converter has been a hot topic in power electronics due to the increasing need in applications like electric vehicles, aircraft and aerospace, where light weight and/or a low volume is usually a must. There are many challenges due to the complicated relationships in a three-phase power converter system. In addition, with the emerging SiC de...

A study of the fundamental of operation of a three-phase AC-DC power converter that uses Zero-Voltage Transition (ZVT) together with Space Vector Pulse Width Modulation (SVPWM) is presented. The converter is basically an active rectifier divided into two converters: a matrix converter and an H bridge, which transfer energy through a high-frequency transformer, resulting in a modular AC-DC wirel...

This paper proposes a four port three input-dc-dc boost converter for hybridising two photovoltaic systems and a storage medium. Three unidirectional ports are utilised to interface the converter with the two input sources and the output load. A bidirectional port interfaces the converter with the storage system. The two sources individually or simultaneously supply the load and charge the batt...

background: the widespread use of toluene and its consequent adverse effects on health and specially its chronic effects on the central nervous system has resulted in many studies being carried out on the methods that can control and reduce toluene vapors in the airflow. the objective of this study is to assess the effectiveness of the catalytic ozonation process in the removal of toluene from ...

In view of the well known core equivalence results in atomless economies, coincidence of market game equilibrium allocations with competitive allocations is tantamount to a three way equivalence between market game mechanisms, competitive equilibria and the core. Based on this idea I propose an equilibrium refinement of market games which allows me to use the core equivalence machinery to provi...

An Isolated ZVS/ZCS bidirectional DC-DC converter for DC Uninterruptable Power supplies is presented in this paper. The usual way to avoid a computer shutdown during the mains failure is to connect an ac uninterruptible power supply (UPS). Alternatively, in this paper, a simple and high efficiency dc UPS is presented by an isolated bidirectional soft-switching dc-dc converter. The bidirectional...

ABSTRACT: In the power generation sector, Natural Resources like Solar, Wind, Tidal, Geothermal, Hydro etc have always played a very important role. Out of these solar PV (photo voltaic) is most popular due to its significant advantages. However the solar radiation never remains constant. It keeps on varying throughout the day. In this paper, single 60 W solar PV panel along with boost converte...
