Electrical Power

01/15/2017 12:42 PM

please help me in understanding this line !

The addition of power can be performed inside the core of the transformer Instead of connecting all renewable sources in parallel on a single DC bus by the produced magnetic flux.

You can raise or lower the voltage with a transformer....

Clearly the OP's transformer core is comprised of magnetic monopoles.

Depends on how you slice it (or in electrical terms chop it into pulses).

You can have the best ignition coil but it will not work just connecting DC. Points and condenser must work, too. In that sense, it is no longer DC. - JHF

A DC signal converted into a pulse wave (or pulse train) of near constant amplitude is still considered DC in my opinion.

Lynn,

Are you a struggling electrician, or are you an electrician at all? I seem to recall that you are a parking and traffic technitian. Do you think electricians come here to get your advice? If this OP were in fact a struggling electrician, why would that make you think that he is not welcome? You seem to think you are welcome, and you are, even though you are not an electrician. It puzzles.

Yeah, me too, out of concern for his safety, which I rather suspect is also your reason for asking. It is one thing to be a student asking these questions, quite another for someone out in the field whose lack of knowledge could lead to serious injury or even death; his own and/or others'. Contrary to what has been suggested by some of the other comments, I don't see that you have said anywhere he is unwelcome here.

Re: electrical power

He's referring to a MISO (Multiple Input Single Output) DC-DC converter where there are multiple switched DC sources, each with its own winding all on a common core, rather than the traditional topology of multiple DC sources which feed a common bus.

The transformer acts as a flux collector feeding into a single output winding.

From this paper.

Well, that escalated quickly.

I was scrolling down, reading all the other replies, and wondering what is wrong with people, because their anwers were not even close.

Anyhow, I think this topic might require a simple drawing, but then, I cannot do that because I am on my phone.

<...The addition of power can be performed inside the core of the transformer Instead of connecting all renewable sources in parallel on a single DC bus by the produced magnetic flux...>

There are errors in the statement. It is not possible to determine at first reading whether there is one sentence or two. One possibility is that there is a missing full-stop after <...transformer...>; the other is that the capitalised <...Instead...> is a mistake.

  • If the full-stop is truly missing and inserted in correction, then the second phrase beginning with <...Instead...> is incomplete and one would expect the alternative to be detailed following the word <...flux...>.
  • If the capitalised <...Instead...> is a mistake, then one doesn't need to detail the alternative further, however, the phrase as then-written, though rectified grammatically, does not convey any meaning.

Until this is rectified, the full meaning of the statement(s) cannot come through. Even were the error(s) rectified, there is still the possibility that the meaning will not come through.

The recommendation, therefore, is to go back to the source of the statement(s) and re-assess.

I reckon he's manually translating from Arabic, a pretty tough job if you're not fluent. Now if he posted his question in Arabic (or whichever tongue he actually speaks) we might have a better chance running it through Google Translate (or not. Sometimes G.T. really mangles things). There also may be others on CR4 who speak his language, are more fluent with English and could lend a hand. As a test, CR4's editor does allow posting of Arabic script but it gets the justification wrong:

هل تتحدث العربية؟

ie, "Do you speak Arabic?" (courtesy G.T.)

Now, mind you it was a test script, for my benefit, to see if CR4's editor could handle it. Any old script would've done, though I suppose I could've posted this instead:

The addition of power can be performed inside the core of the transformer by the produced magnetic flux - instead of connecting all renewable sources in parallel on a single DC bus.

Looks like "human wordprocessor virus" in the original article quoted by the poster. "Proof reading" is a lost function of communication.

While it appears as though RAMConsult has figured out what you are asking, let me offer some advise for future posts. The Dean of Engineering at my college once said, 'English is a foreign language. (now this was in the USA) We are engineers and we speak with symbols, mathematical formulas and drawings." It would be best for you to include a drawing of the device in question. That would end the myriad of silly and demeaning responses your post generated.

Re: electrical power

And, would it also not be unreasonable to ask that those who come here seeking answers to relatively elementary questions disclose, in the very beginning, that they are students and that they are not "a struggling electrician unskilled in his trade".

After all, below could well be the result of giving advice to someone without the necessary skills and background to use the information so gleefully provided to prove the technical prowess of those so willing to give answers to total strangers?

Finally, as in most cases, we have a speculative argument between many as to what the question really is, while offering our respective opinions of

1. What we BELIEVE the question was and

2. What you each individually BELIEVE is the one and only correct answer.

Where, exactly does this leave the poor student (if indeed they are a student)?

Certainly not with a clear, correct answer!

At least you give some advice to the OP, unlike PFR who merely wastes time.

First - am I missing something here on this site? This isn't the first time a GA response seems to be based on far more information than the original post contained. How did RAMConsultant know what paper the line was from? You also seem to have a knack for this, as you picked up rather quickly that this was a student. Is there additional info posted somewhere else that I am missing?

As to your response to me - I have no problem with discerning student/professional. I just think a bit more info, in this case a reference to the paper RAMConsultant apparently knew of, or at least a good schematic would have avoided the very first response on the Allen Bradley what ever it is. (that is about 15 years old as I recall and I had a Siemens rep show it to me once) I am not getting into your argument with PFR. Just reminding folks that one needs to post some more details, preferably schematics if a question is going to be rather vague. And yes, even USA born and raised can consider English a foreign language when it comes to engineering explanations.

Actually OP's question is a direct quote from an article in the IJERST (International Journal of Engineering Sciences & Research Technology, a "pay to publish" magazine from India). The content seemed too academic to come from a student, and of course had he googled on it himself he would have gotten the article plus a few others on the topic.
