The switching action is independent of the power actually being dissipated in the load. An advantage of this method is that it may be applied to AC or DC loads being supplied from an AC supply. EPC was established in 2007 in Jeddah with main activities in the Distribution of different type of electrical materials , manufacturing of all types of electrical panel bored and electrical and maintenance works The factory is equipped with the most modern machinery , i.e. Apart from poor efficiency, an undesirable aspect of this method is the manner in which the load voltage varies if the load current varies. This course is an introductory subject in the field of electric power systems and electrical to mechanical energy conversion. },{ { Switched Control. Power Control Engineers is a Newcastle based design, consulting and project management company specialising in electrical power engineering. Once turned on, these devices offer very little resistance and hence dissipate very little power, resulting in high efficiencies. The waveforms in, For high power, the thyristor will be turned on for a larger number of cycles than it is off, and the reverse applies for low power. To control the load, power must be dissipated in the rheostat. The advantages of the method are that it is simple and efficient, while it has the disadvantages that it is costly for medium to high power loads, has poor load regulation and provides control only in discrete steps.
