BARGAINING POWER OF SUPPLIER • Bargaining power is the ability to influence the setting of prices. • The more concentrated and controlled the supply‚ the more power it wields against the market. • Monopolistics or quasi-monopolistic suppliers will use their power to extract better terms (higher profit margins or ) at the expense of the market. • In a truly competitive market‚ no one supplier can set the prices. Aggregation of Supply • Suppliers can group to wield more bargaining power. • This

in most countries is AC with a frequency of 60 hertz (60 complete cycles per second)‚ although in some countries it is 50 Hz. The radio-frequency (RF) current in antennas and transmission lines is another example of AC. The usual waveform of an AC power circuit is a sine wave. In certain applications‚ different waveforms are used‚ such as triangular or square waves. DC (direct current) - DC (direct current) is the unidirectional flow or movement of electric charge carriers (which are usually electrons)

CHAPTER 1 INTRODUCTION 1.1 GENERAL Nowadays‚ there is a demand of power supply. As an electrical engineer‚ it is necessary to design system with low cost‚ reduced losses and higher efficiency. This paper proposes nine-switch converter with single controller‚ rather than using 12 switches for operation of drives separately. In electrical vehicle drives mostly AC motors are used. It is because of its well known advantages like simplicity‚ reliability‚ lack of mechanical commutator

INTRODUCTION The matrix converter offers an all silicon solution for AC-AC power conversion. The circuit consists o an array of hi-directional switches arranged so that any of the output lines of the f converter can be connected to any of the input lines. Figure 1 shows a typical three-phase to threephase matrix converter‚ with

Besides‚ a good electrical system provides high quality of service to the guest and facilitates the staff working environment. Source of electricity‚ power distribution systems‚ control devices and connected equipments are the essential elements of an electrical system. All of the above mentioned components must be probably built and maintained. In other words‚ a proper maintenance program can act as

recent years‚ the continuous and rapid growth in population in urban areas and growth of industrialization in Pakistan has affected the demand of electricity very badly in country. The demand of the electricity in country is much greater than the supply and production of electricity in country. This situation causes electricity crisis in Pakistan. The duration of load shedding reached14 to 18 hours a day. Shortage of electricity has reached 5500 MW‚ 12 to 14 hours in urban areas and 18 hours in

UPS systems are triggered automatically when the power supply is interrupted between the mains and the equipment. The presence of UPS systems enables network administrators to restore the system or execute an alternative solution in the data center during the period when the power backup is supplied. Covered
