Ah, but there's the problem - it's wrong! (well technically, anyway)

It's first paragraph says: "An Inverter is an electronic device that converts one voltage to a higher voltage. Travellers usually want to convert 12 volts DC (Direct Current) to 240 volts AC (Alternating Current)."

A transformer is used to convert one voltage to another.

In actual fact an inverter is an electronic device that convert one power source to another - typically a DC source to an AC source, but also one AC frequency to another AC frequency or two phase to three phase or vice-versa.

i'm with andrew
(not neccessarily the link)

inverters in my book change dc to ac or vice versa. the frequency stuff is just a bit of extra hardware in the box which may be needed to suit the output requirements.
Typically the more herzt the faster something whizzes along

Andrew, it is grammatically impossible to convert from one source to another source.

An inverter is an electronic device that convert one power source to another - typically a DC source to an AC output, but also one AC frequency to another AC frequency or two phase to three phase or vice-versa.

Now as far as two phase to three phase goes I am not so sure.

Now, there is a one for the record ... I am being stood up on the grammatically impossible.

I beg to differ ... it is a grammatical contraction which is a common form of speech in Australia, where what a well understood phrase is contracted to make do for the same purpose.

Saying that you are "converting one source to another source" is a contraction of "converting the power characteristics of the power from one source to create a new power source with a different set of power characteristics".

Now even you would understand that that it is, if nothing else, gramattically efficient.

Why the situation is any different in the phase change situation, I can't begin to apprehend.

Cheers
Andrew.

Grammatically efficient as it is, it is still grammatically impossible as conversion requires a source and a output :) Contractions are, by nature, grubby rationalisations of lazy grammar, however widespread in use they are.

And I think you are having a lend with apprehend hahahahah, I thunk you mean comprehend. In the case of phasing there are phase shifts to consider. Two phase can be either 415v ph to ph or 480v ph to ph depending on the phase shift. And inverter may have trouble making a phase shift I think. Going from three phase to two phase is easy for the same phase shift, but even three phase inverters are actually three single phase inverters.

Oh and I am quite chuffed at creating one for te books.

Cheers Andrew

No, I mean apprehend ...

ap·pre·hend /ˌæprɪˈhɛnd/ Pronunciation Key - [ap-ri-hend]
–verb (used with object)

1. to take into custody; arrest by legal warrant or authority: The police apprehended the burglars.
2. to grasp the meaning of; understand, esp. intuitively; perceive.
3. to expect with anxiety, suspicion, or fear; anticipate: apprehending violence.
–verb (used without object) 4. to understand.
5. to be apprehensive, suspicious, or fearful; fear.

So I meant meaning "2".

I think in your phase shifting you are getting very specific to your experience with common electrical systems, as with your appreciation of inverters, and are failing to make the phase shift to more general applications of technical term inverter.

In an electical engineering sense, going from three phase to two phase or vice versa, is technically not difficult - I mean, it is easy to draw a diagram for it, but finding the right components and making it work to the level of quality required of electicity distributions may certainly be harder.

I was surprised to see you use the word chuffed - were you trying to impress with a sense of imperious British decency or to obfuscate with ambiguity? The word has two meanings which are complete opposites (see dictionary.reference.com/browse/chuffed).

Cheers
Andrew.

lol I didnt know the use of the second meaning as you quote above, well learned something new today, that comprehend and apprehend can mean the same thing.

Thats good my persipicacious friend. And trust the poms to use a word that means the oppposite of itself at the same time. I meant that I am pleasantly amused and pleased. Obfuscation obviated.

The phase shift stuff is just normal electrical theory nothing specific.

To go from three phases to two phases depends on the application, i.e. do you want to run a two phase 480v motor, in which case you'd need to worry about phase shift.

Bonz,

Actually it is entirely grammatically possible to convert from one source to another. Perhaps you could argue that Andrew is guilty of a logical fallacy or even stating a physical impossibility, but it does not relate to grammar.

It is interesting to note that you think contractions are, by nature, grubby rationalisations of lazy grammar. Presumably you don't extend the same rules to the use of 'emoticons' or other common contractions? However widespread in use they are by you and just about anyone who uses this type of forum to communicate. Now there is a glaring contradiction.

Cheers,

Matt.

Of course! I now reaslise the error of my ways, it is LOGIC that is at fault and of course mostly my own, Andrew is indeed a wordsmith and teacher of high skill and in the end it is impossibility that is at question here.

Oh and I dont consider :) to be an emoticon, its a smiley.

A "logical fallacy" ... well, would you rather an illogical fallacy?

With such obfuscation with oxymorons I think I shall defenstrate.

Ciao for now,
Andrew.

who gives a toss about what grammatically was meant or was not

lets get back to the inverter issue

Yes Andrew I am definitely an Oxymoron, not however a Migmoron or an Arcmoron, but those Oxy units frighten the carp outta me
