This article shows the various control signals that are usually used for dimming ballasts and the criteria for the microcontroller to distinguish the signals. The dimming interface is a manufacturer-specific digital interface that is implemented in digital controlled ballasts. Dimming interface can protect the overvoltage by use of high-voltage current limiter circuit. Features of dimming interfac... View full abstract»

This work presents a series active filter system for three-phase, four-wire distribution systems to alleviate the overloading of the neutral conductor. The active filter system employs a voltage sources inverter connected in series with a neutral conductor to suppress the excessive current harmonics. Theoretical analysis shows that series active filter system are more suitable than shunt active fi... View full abstract»

This work presents an analytical methodology for selecting the most economical mix of drivers for large mechanical load and power generation for offshore production in the Gulf of Mexico. These method accounts for CAPEX, life-cycle costs and the effect of emissions and production availability in the selection of drivers and associated equipment. Result of driver studies have shown that all electri... View full abstract»

This work deals with Westinghouse research laboratory in East Pittsburgh. Westinghouse was one of the first large industrial corporations to build a laboratory devoted to science-based research separate from the manufacturing plant with the intent of shielding it from the pressures of solving immediate problems for the operating divisions. The laboratory expanded rapidly and many of the projects w... View full abstract»

Optimization of electrostatic separation processes demands the control of a multitude of factors, including the characteristics of the granular mixtures to be sorted, the feed rate, the configuration of the electrode system, the applied high-voltage and the environmental conditions. The Taguchi's experimental designs presented in this article clearly prove that the linear-interaction models of the... View full abstract»

The work presents a multiphase DC-DC converter aimed to equip a C segment, next generation car having a 42/14 V automotive dual-voltage electric power system. The inverted power flow can be obtained by an additional DC-DC converter working in step-up mode or by using electronic interface based on a bilateral converter topology. The experimental result show that proposed solution has greater effici... View full abstract»
