one of the most important number sequences in mathematics is fibonacci sequence. fibonacci sequence except for mathematics is applied to other branches of science such as physics and arts. in fact, between anesthetics and this sequence there exists a wonderful relation. fibonacci sequence has an importance characteristic which is the golden number. in this thesis, the golden number is observed ...

Most existing power  converters and industrial motor drive systems draw non-sinusoidal currents from the supply. Non-sinusoidal currents contained harm harmonics disturb the power supply which it causes serious concern for reliability. Other equipments that use the same power supply are adversely affected. This paper suggests the operation and performance of a new modified AC/DC converter that ...

This paper discusses the circuit theory aspects of power factor correction in switching converter circuits. The discussion begins with an examination of the requirement of power factor correction in dc=dc converters. Using the concept of zero-order converter circuits, su cient conditions for a dc=dc converter circuit to provide power factor correction are derived. The duality principle is appli...

Power factor correction (PFC) is a technique of counteracting the undesirable effects of electric loads that create a power factor that is less than one. Power factor correction may be applied either by an electrical power transmission utility to improve the stability and efficiency of the transmission network or correction may be installed by individual electrical customers to reduce the costs...

Energetic life-sustaining needs, such as electrical power, are essential for everyday existence. It is commonly used in residential, industrial, farming, and medical facilities. Life without energy minimal. Despite the vital need electricity demand, losses curtailments additional bills still problems. Power factor correction a method to fix or minimize mentioned Automated power (APFC) will prec...
