The analysis of supply current at minimum duty ratio (i.e., supply voltage as 220 V and dc link voltage as 50 V) is carried out for different values of the inductor (Li1 and Li2). Fig. 4 shows the supply current at the input inductor’s value as Lic, Lic/2, Lic/5, and Lic/10, respectively. The supply current at higher values of the input side inductor is highly distorted due to the inability of the converter to operate in DICM at peak values of supply voltages. Hence, the values of inductors Li1 and Li2 are selected around 1/10th of the critical inductance and are taken as 35 μH.
1. Electrician Do you have a circuit breaker that keeps tripping, a broken outlet or a damaged wiring? Electricity plays an important role in our lives. Lost power means lost time, lost productivity and in some cases, lost money. So when electrical problems occur in your home, or when it comes to electrical upgrade, you need the most reliable team of electricians.
Title: Why you need someone who can fix a vehicle. Introduction A. Attention Getter: Vehicles are a great asset in this post-apocalyptic world, but they will eventually breakdown, and there is no way to prevent that. B. Thesis: That's why you should choose me for your bomb shelter because with my knowledge of vehicle repair, when the eventual breakdown does occur, it won't leave you stranded. C. Organizational Statement: I will talk about how essential vehicles are to surviving the wasteland, why you need someone who can fix vehicles, and how my skills will help you when those vehicles breakdown and parts are needed.
Using nuclear to produce energy is preferable compared to other system burning of fossil fuels, which causes so much of pollution with carbon dioxide. In addition to the process of nuclear system, the disposal of nuclear waste, which results during the generation of nuclear power is much easier to deal with. The reason is because it is just dumped in to a geological site where it decays over a period of time and has not negative impact on the environmental. This is also the main advantage of nuclear energy compared to the other chemical used generating system, which cause much more poisonous gases. Most of the generating energy system came up with problem that lack of source to generate enough, however, the source of nuclear power is uranium, which is available in abundance in the crust of the Earth with major deposits being uncovered in Canada and Australia.
Risk, one of the most important consideration when developing a technology, plays a very large role in nuclear power. In my opinion, nuclear power should be abolished because of the many risks that it brings when used. One of the biggest risk that a nuclear plant can bring is a meltdown or plant leakage, which results in a catastrophic damage. On top of that, problems in storing nuclear
DC generators and AC generator. 3. With the use of transformers, we can transform and transmit AC electricity over a long path with less loss of power. 4. Electromagnetic flow meters can be used to measure the blood rate using magnetic fields which are applied to electrically conducting fluids.
These systems can assist with lighting, heating, ventilation, transportation, and production of power (Prospects). Originally I just loved solving those puzzles my parents got me for the fun of accomplishing something, however I now know that there is so much more I can do as an electrical engineer. Soon enough as I moved on to a later stage in my life I
Cable sizing is the process of selecting appropriate sizes for electrical power cable conductors. Cable sizing is one of the most important decisions that must be taken wisely. The engineer must take into considerations many factors since it has a great effect on the electrical system. Cable sizes are typically described in terms of cross-sectional area. 3.1.1 The Basics of Cable Sizing.
Nuclear power plants use this use the heat that is created by fission to heat water that spins their turbines (“Nuclear Energy”). The potential is limitless, and it should be realized as they have low greenhouse gas emissions, are efficient, powerful, cheap and reliable. Positives outweigh the negatives, and we should keep on using nuclear energy. Firstly, nuclear power generation has low greenhouse gas emissions, which make it good for the environment. The actual fission
SinΦ. Reactive power, or VAr, is not by any stretch of the really power at all represents the product of volts and amperes that are out-of-phase with one another. The measure of reactive power present in an AC circuit will depend up on the phase shift or phase angle between the voltage and the current and simply like active power, reactive power is positive when it is "supplied" and negative when it is
