ABSTRACT
The need to control the emissions from automobiles gave rise to the computerization of the automobile. Hydrocarbons, carbon monoxide and oxides of nitrogen are created during the combustion process and are emitted into the atmosphere from the tail pipe. There are also hydrocarbons emitted as a result of vaporization of gasoline and from the crankcase of the automobile. The clean air act of 1977 set limits to the amount of each of these pollutants that could be emitted from ....etc

This article describes the Voltage swell and overvoltage compensation problems in a diode-bridge rectifier supported transformerless-coupled
dynamic voltage restorer (DVR). applying conventional in-phase or phase-invariant boosting method in case of condition of swell or overvoltage, may cause a a rapid rise in dc-link voltage which may ultimately lead to the damage of the storage capacitors and switching devices, and increase the switching loss. The minimum energy injection scheme is unable to solve these problems. Here, a novel unidirectio ....etc

EFFECTS OF VOLTAGE SAGS, SWELL AND OTHER DISTURBANCES ON
ELECTRICAL EQUIPMENT AND THEIR ECONOMIC IMPLICATIONS



ABSTRACT

Poor power quality has come to stay in most parts of the
world. In most part of Africa, especially in Nigeria, it is
almost normal not to have good clean power free from
disturbances. If power equipment and loads could talk or
express feelings, I am sure they would have made a big
protest against the great injustices imposed on them. A
survey was carried out amongst 15 multi-nation ....etc
